CVE-2025-40916: Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)

Mojolicious::Plugin::CaptchaPNG version 1.05 for Perl uses a weak random number source for generating the captcha. That version uses the built-in rand function for generating the captcha text as well as image noise, which is insecure...

CVE-2025-40915: Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)

Mojolicious::Plugin::CSRF 1.03 for Perl uses a weak random number source for generating CSRF tokens. That version of the module generates tokens as an MD5 of the process id, the current time, and a single call to the built-in rand function...

CVE-2024-45751

tgt aka Linux target framework before 1.0.93 attempts to achieve entropy by calling rand without srand. The PRNG seed is always 1, and thus the sequence of challenges is always identical...

CVE-2024-41594

An issue in DrayTek Vigor310 devices through 4.3.2.6 allows an attacker to obtain sensitive information because the httpd server of the Vigor management UI uses a static string for seeding the PRNG of OpenSSL...
