CVSS v3.1 |
| An insufficient entropy vulnerability was found in glibc. The getrandom and arc4random family of functions may return predictable randomness if these functions are called again after the fork, which happens concurrently with a call to any of these functions. |
| Business::OnlinePayment::StoredTransaction versions through 0.01 for Perl uses an insecure secret key.
Business::OnlinePayment::StoredTransaction generates a secret key by using a MD5 hash of a single call to the built-in rand function, which is unsuitable for cryptographic use.
This key is intended for encrypting credit card transaction data. |
| Cloudreve is a self-hosted file management and sharing system. Prior to version 4.13.0, the application uses the weak pseudo-random number generator math/rand seeded with time.Now().UnixNano() to generate critical security secrets, including the secret_key, and hash_id_salt. These secrets are generated upon first startup and persisted in the database. An attacker can exploit this by obtaining the administrator's account creation time (via public API endpoints) to narrow the search window for the PRNG seed, and use known hashid to validate the seed. By brute-forcing the seed (demonstrated to take <3 hours on general consumer PC), an attacker can predict the secret_key. This allows them to forge valid JSON Web Tokens (JWTs) for any user, including administrators, leading to full account takeover and privilege escalation. This issue has been patched in version 4.13.0. |
| Cryptographic Flaw in PDFium in Google Chrome prior to 147.0.7727.55 allowed an attacker to read potentially sensitive information from encrypted PDFs via a brute-force attack. (Chromium security severity: Medium) |
| Auth0-PHP is a PHP SDK for Auth0 Authentication and Management APIs. From version 8.0.0 to before version 8.19.0, in applications built with the Auth0 PHP SDK, cookies are encrypted with insufficient entropy, which may result in threat actors brute-forcing the encryption key and forging session cookies. This issue has been patched in version 8.19.0. |
| The BuddyForms plugin for WordPress is vulnerable to Email Verification Bypass in all versions up to, and including, 2.8.9 via the use of an insufficiently random activation code. This makes it possible for unauthenticated attackers to bypass the email verification. |
| The CMS Commander plugin for WordPress is vulnerable to authorization bypass due to the use of an insufficiently unique cryptographic signature on the 'cmsc_add_site' function in versions up to, and including, 2.287. This makes it possible for unauthenticated attackers to the plugin to change the '_cmsc_public_key' in the plugin config, providing access to the plugin's remote control functionalities, such as creating an admin access URL, which can be used for privilege escalation. This can only be exploited if the plugin has not been configured yet, however, if combined with another arbitrary plugin installation and activation vulnerability, the impact can be severe. |
| The WooCommerce - Social Login plugin for WordPress is vulnerable to Email Verification in all versions up to, and including, 2.6.2 via the use of insufficiently random activation code. This makes it possible for unauthenticated attackers to bypass the email verification. |
| The WP Reset – Most Advanced WordPress Reset Tool plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.0 via the use of insufficiently random snapshot names. This makes it possible for unauthenticated attackers to extract sensitive data including site backups by brute-forcing the snapshot filenames. Please note that the vendor does not plan to do any further hardening on this functionality. |
| The File Manager plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 7.2.1 due to insufficient randomness in the backup filenames, which use a timestamp plus 4 random digits. This makes it possible for unauthenticated attackers, to extract sensitive data including site backups in configurations where the .htaccess file in the directory does not block access. |
| PAGI::Middleware::Session::Store::Cookie versions through 0.001003 for Perl generates random bytes insecurely.
PAGI::Middleware::Session::Store::Cookie attempts to read bytes from the /dev/urandom device directly. If that fails (for example, on systems without the device, such as Windows), then it will emit a warning that recommends the user install Crypt::URandom, and then return a string of random bytes generated by the built-in rand function, which is unsuitable for cryptographic applications.
This modules does not use the Crypt::URandom module, and installing it will not fix the problem.
The random bytes are used for generating an initialisation vector (IV) to encrypt the cookie.
A predictable IV may make it easier for malicious users to decrypt and tamper with the session data that is stored in the cookie. |
| Amon2 versions before 6.17 for Perl use an insecure random_string implementation for security functions.
In versions 6.06 through 6.16, the random_string function will attempt to read bytes from the /dev/urandom device, but if that is unavailable then it generates bytes by concatenating a SHA-1 hash seeded with the built-in rand() function, the PID, and the high resolution epoch time. The PID will come from a small set of numbers, and the epoch time may be guessed, if it is not leaked from the HTTP Date header. The built-in rand function is unsuitable for cryptographic usage.
Before version 6.06, there was no fallback when /dev/urandom was not available.
Before version 6.04, the random_string function used the built-in rand() function to generate a mixed-case alphanumeric string.
This function may be used for generating session ids, generating secrets for signing or encrypting cookie session data and generating tokens used for Cross Site Request Forgery (CSRF) protection. |
| An issue in Eufy Homebase 2 version 3.3.4.1h allows a local attacker to obtain sensitive information via the cryptographic scheme. |
| WWW::OAuth 1.000 and earlier for Perl uses the rand() function as the default source of entropy, which is not cryptographically secure, for cryptographic functions. |
| Maypole versions from 2.10 through 2.13 for Perl generates session ids insecurely. The session id is seeded with the system time (which is available from HTTP response headers), a call to the built-in rand() function, and the PID. |
| A weakness in the web interface’s application layer encryption in VX800v v1.0 allows an adjacent attacker to brute force the weak AES key and decrypt intercepted traffic. Successful exploitation requires network proximity but no authentication, and may result in high impact to confidentiality, integrity, and availability of transmitted data. |
| Crypt::RandomEncryption for Perl version 0.01 uses insecure rand() function during encryption. |
| Net::NSCA::Client versions through 0.009002 for Perl uses a poor random number generator.
Version v0.003 switched to use Data::Rand::Obscure instead of Crypt::Random for generation of a random initialisation vectors.
Data::Rand::Obscure uses Perl's built-in rand() function, which is not suitable for cryptographic functions. |
| Non-random values for ticket_age_add in session tickets in crypto/tls before Go 1.17.11 and Go 1.18.3 allow an attacker that can observe TLS handshakes to correlate successive connections by comparing ticket ages during session resumption. |
| Smolder versions through 1.51 for Perl uses insecure rand() function for cryptographic functions.
Smolder 1.51 and earlier for Perl uses the rand() function as the default source of entropy, which is not cryptographically secure, for cryptographic functions.
Specifically Smolder::DB::Developer uses the Data::Random library which specifically states that it is "Useful mostly for test programs". Data::Random uses the rand() function. |
