| CVE-2021-39225 | 1 Nextcloud | 1 Deck | 2024-11-21 | 8.1 High |
| Nextcloud is an open-source, self-hosted productivity platform. A missing permission check in Nextcloud Deck before 1.2.9, 1.4.5 and 1.5.3 allows another authenticated users to access Deck cards of another user. It is recommended that the Nextcloud Deck App is upgraded to 1.2.9, 1.4.5 or 1.5.3. There are no known workarounds aside from upgrading. | ||||
| CVE-2021-39219 | 2 Bytecodealliance, Fedoraproject | 2 Wasmtime, Fedora | 2024-11-21 | 6.3 Medium |
| Wasmtime is an open source runtime for WebAssembly & WASI. Wasmtime before version 0.30.0 is affected by a type confusion vulnerability. As a Rust library the `wasmtime` crate clearly marks which functions are safe and which are `unsafe`, guaranteeing that if consumers never use `unsafe` then it should not be possible to have memory unsafety issues in their embeddings of Wasmtime. An issue was discovered in the safe API of `Linker::func_*` APIs. These APIs were previously not sound when one `Engine` was used to create the `Linker` and then a different `Engine` was used to create a `Store` and then the `Linker` was used to instantiate a module into that `Store`. Cross-`Engine` usage of functions is not supported in Wasmtime and this can result in type confusion of function pointers, resulting in being able to safely call a function with the wrong type. Triggering this bug requires using at least two `Engine` values in an embedding and then additionally using two different values with a `Linker` (one at the creation time of the `Linker` and another when instantiating a module with the `Linker`). It's expected that usage of more-than-one `Engine` in an embedding is relatively rare since an `Engine` is intended to be a globally shared resource, so the expectation is that the impact of this issue is relatively small. The fix implemented is to change this behavior to `panic!()` in Rust instead of silently allowing it. Using different `Engine` instances with a `Linker` is a programmer bug that `wasmtime` catches at runtime. This bug has been patched and users should upgrade to Wasmtime version 0.30.0. If you cannot upgrade Wasmtime and are using more than one `Engine` in your embedding it's recommended to instead use only one `Engine` for the entire program if possible. An `Engine` is designed to be a globally shared resource that is suitable to have only one for the lifetime of an entire process. If using multiple `Engine`s is required then code should be audited to ensure that `Linker` is only used with one `Engine`. | ||||
| CVE-2021-39206 | 2 Envoyproxy, Pomerium | 2 Envoy, Pomerium | 2024-11-21 | 8.6 High |
| Pomerium is an open source identity-aware access proxy. Envoy, which Pomerium is based on, contains two authorization related vulnerabilities CVE-2021-32777 and CVE-2021-32779. This may lead to incorrect routing or authorization policy decisions. With specially crafted requests, incorrect authorization or routing decisions may be made by Pomerium. Pomerium v0.14.8 and v0.15.1 contain an upgraded envoy binary with these vulnerabilities patched. This issue can only be triggered when using path prefix based policy. Removing any such policies should provide mitigation. | ||||
| CVE-2021-39204 | 2 Envoyproxy, Pomerium | 2 Envoy, Pomerium | 2024-11-21 | 7.5 High |
| Pomerium is an open source identity-aware access proxy. Envoy, which Pomerium is based on, incorrectly handles resetting of HTTP/2 streams with excessive complexity. This can lead to high CPU utilization when a large number of streams are reset. This can result in a DoS condition. Pomerium versions 0.14.8 and 0.15.1 contain an upgraded envoy binary with this vulnerability patched. | ||||
| CVE-2021-39194 | 1 Kaml Project | 1 Kaml | 2024-11-21 | 4.3 Medium |
| kaml is an open source implementation of the YAML format with support for kotlinx.serialization. In affected versions attackers that could provide arbitrary YAML input to an application that uses kaml could cause the application to endlessly loop while parsing the input. This could result in resource starvation and denial of service. This only affects applications that use polymorphic serialization with the default tagged polymorphism style. Applications using the property polymorphism style are not affected. YAML input for a polymorphic type that provided a tag but no value for the object would trigger the issue. Version 0.35.3 or later contain the fix for this issue. | ||||
| CVE-2021-39184 | 1 Electronjs | 1 Electron | 2024-11-21 | 6.8 Medium |
| Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. A vulnerability in versions prior to 11.5.0, 12.1.0, and 13.3.0 allows a sandboxed renderer to request a "thumbnail" image of an arbitrary file on the user's system. The thumbnail can potentially include significant parts of the original file, including textual data in many cases. Versions 15.0.0-alpha.10, 14.0.0, 13.3.0, 12.1.0, and 11.5.0 all contain a fix for the vulnerability. Two workarounds aside from upgrading are available. One may make the vulnerability significantly more difficult for an attacker to exploit by enabling `contextIsolation` in one's app. One may also disable the functionality of the `createThumbnailFromPath` API if one does not need it. | ||||
| CVE-2021-39179 | 1 Dhis2 | 1 Dhis 2 | 2024-11-21 | 8.8 High |
| DHIS 2 is an information system for data capture, management, validation, analytics and visualization. A SQL Injection vulnerability in the Tracker component in DHIS2 Server allows authenticated remote attackers to execute arbitrary SQL commands via unspecified vectors. This vulnerability affects the `/api/trackedEntityInstances` and `/api/trackedEntityInstances/query` API endpoints in all DHIS2 versions 2.34, 2.35, and 2.36. It also affects versions 2.32 and 2.33 which have reached _end of support_ - exceptional security updates have been added to the latest *end of support* builds for these versions. Versions 2.31 and older are unaffected. The system is vulnerable to attack only from users that are logged in to DHIS2, and there is no known way of exploiting the vulnerability without first being logged in as a DHIS2 user. The vulnerability is not exposed to a non-malicious user - the vulnerability requires a conscious attack to be exploited. A successful exploit of this vulnerability could allow the malicious user to read, edit and delete data in the DHIS2 instance. There are no known exploits of the security vulnerabilities addressed by these patch releases. Security patches are available in DHIS2 versions 2.32-EOS, 2.33-EOS, 2.34.7, 2.35.7, and 2.36.4. There is no straightforward known workaround for DHIS2 instances using the Tracker functionality other than upgrading the affected DHIS2 server to one of the patches in which this vulnerability has been fixed. For implementations which do NOT use Tracker functionality, it may be possible to block all network access to POST to the `/api/trackedEntityInstances`, and `/api/trackedEntityInstances/query` endpoints as a temporary workaround while waiting to upgrade. | ||||
| CVE-2021-39165 | 1 Chachethq | 1 Cachet | 2024-11-21 | 8.1 High |
| Cachet is an open source status page. With Cachet prior to and including 2.3.18, there is a SQL injection which is in the `SearchableTrait#scopeSearch()`. Attackers without authentication can utilize this vulnerability to exfiltrate sensitive data from the database such as administrator's password and session. The original repository of Cachet <https://github.com/CachetHQ/Cachet> is not active, the stable version 2.3.18 and it's developing 2.4 branch is affected. | ||||
| CVE-2021-39164 | 2 Fedoraproject, Matrix | 2 Fedora, Synapse | 2024-11-21 | 3.1 Low |
| Matrix is an ecosystem for open federated Instant Messaging and Voice over IP. In versions 1.41.0 and prior, unauthorised users can access the membership (list of members, with their display names) of a room if they know the ID of the room. The vulnerability is limited to rooms with `shared` history visibility. Furthermore, the unauthorised user must be using an account on a vulnerable homeserver that is in the room. Server administrators should upgrade to 1.41.1 or later in order to receive the patch. One workaround is available. Administrators of servers that use a reverse proxy could, with potentially unacceptable loss of functionality, block the endpoints: `/_matrix/client/r0/rooms/{room_id}/members` with `at` query parameter, and `/_matrix/client/unstable/rooms/{room_id}/members` with `at` query parameter. | ||||
| CVE-2021-39163 | 2 Fedoraproject, Matrix | 2 Fedora, Synapse | 2024-11-21 | 3.1 Low |
| Matrix is an ecosystem for open federated Instant Messaging and Voice over IP. In versions 1.41.0 and prior, unauthorised users can access the name, avatar, topic and number of members of a room if they know the ID of the room. This vulnerability is limited to homeservers where the vulnerable homeserver is in the room and untrusted users are permitted to create groups (communities). By default, only homeserver administrators can create groups. However, homeserver administrators can already access this information in the database or using the admin API. As a result, only homeservers where the configuration setting `enable_group_creation` has been set to `true` are impacted. Server administrators should upgrade to 1.41.1 or higher to patch the vulnerability. There are two potential workarounds. Server administrators can set `enable_group_creation` to `false` in their homeserver configuration (this is the default value) to prevent creation of groups by non-administrators. Administrators that are using a reverse proxy could, with partial loss of group functionality, block the endpoints `/_matrix/client/r0/groups/{group_id}/rooms` and `/_matrix/client/unstable/groups/{group_id}/rooms`. | ||||
| CVE-2021-39156 | 2 Istio, Redhat | 2 Istio, Service Mesh | 2024-11-21 | 8.1 High |
| Istio is an open source platform for providing a uniform way to integrate microservices, manage traffic flow across microservices, enforce policies and aggregate telemetry data. Istio 1.11.0, 1.10.3 and below, and 1.9.7 and below contain a remotely exploitable vulnerability where an HTTP request with `#fragment` in the path may bypass Istio’s URI path based authorization policies. Patches are available in Istio 1.11.1, Istio 1.10.4 and Istio 1.9.8. As a work around a Lua filter may be written to normalize the path. | ||||
| CVE-2021-39155 | 2 Istio, Redhat | 2 Istio, Service Mesh | 2024-11-21 | 8.3 High |
| Istio is an open source platform for providing a uniform way to integrate microservices, manage traffic flow across microservices, enforce policies and aggregate telemetry data. According to [RFC 4343](https://datatracker.ietf.org/doc/html/rfc4343), Istio authorization policy should compare the hostname in the HTTP Host header in a case insensitive way, but currently the comparison is case sensitive. The proxy will route the request hostname in a case-insensitive way which means the authorization policy could be bypassed. As an example, the user may have an authorization policy that rejects request with hostname "httpbin.foo" for some source IPs, but the attacker can bypass this by sending the request with hostname "Httpbin.Foo". Patches are available in Istio 1.11.1, Istio 1.10.4 and Istio 1.9.8. As a work around a Lua filter may be written to normalize Host header before the authorization check. This is similar to the Path normalization presented in the [Security Best Practices](https://istio.io/latest/docs/ops/best-practices/security/#case-normalization) guide. | ||||
| CVE-2021-39138 | 1 Parseplatform | 1 Parse-server | 2024-11-21 | 4.8 Medium |
| Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Developers can use the REST API to signup users and also allow users to login anonymously. Prior to version 4.5.1, when an anonymous user is first signed up using REST, the server creates session incorrectly. Particularly, the `authProvider` field in `_Session` class under `createdWith` shows the user logged in creating a password. If a developer later depends on the `createdWith` field to provide a different level of access between a password user and anonymous user, the server incorrectly classified the session type as being created with a `password`. The server does not currently use `createdWith` to make decisions about internal functions, so if a developer is not using `createdWith` directly, they are not affected. The vulnerability only affects users who depend on `createdWith` by using it directly. The issue is patched in Parse Server version 4.5.1. As a workaround, do not use the `createdWith` Session field to make decisions if one allows anonymous login. | ||||
| CVE-2021-39119 | 1 Atlassian | 4 Data Center, Jira, Jira Data Center and 1 more | 2024-11-21 | 5.3 Medium |
| Affected versions of Atlassian Jira Server and Data Center allow users who have watched an issue to continue receiving updates on the issue even after their Jira account is revoked, via a Broken Access Control vulnerability in the issue notification feature. The affected versions are before version 8.19.0. | ||||
