CVE-2025-40933: Generation of Predictable Numbers or Identifiers

Apache::AuthAny::Cookie v0.201 or earlier for Perl generates session ids insecurely. Session ids are generated using an MD5 hash of the epoch time and a call to the built-in rand function. The epoch time may be guessed, if it is not leaked from the HTTP Date header. The built-in rand function is...

FreeBSD : p5-Crypt-CBC -- Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) (cd7f969e-6cb4-11f0-97c4-40b034429ecf)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the cd7f969e-6cb4-11f0-97c4-40b034429ecf advisory. Lib-Crypt-CBC project reports: Crypt::CBC versions between 1.21 and 3.05 for Perl may use the rand...

CVE-2025-40924: Generation of Predictable Numbers or Identifiers

Catalyst::Plugin::Session before version 0.44 for Perl generates session ids insecurely. The session id is generated from a usually SHA-1 hash of a simple counter, the epoch time, the built-in rand function, the PID and the current Catalyst context. This information is of low entropy. The PID wil...

CVE-2025-40923: Generation of Predictable Numbers or Identifiers

Plack-Middleware-Session before version 0.35 for Perl generates session ids insecurely. The default session id generator returns a SHA-1 hash seeded with the built-in rand function, the epoch time, and the PID. The PID will come from a small set of numbers, and the epoch time may be guessed, if i...

The vulnerability of the rand() function in the Crypt::CBC module of the Perl programming language allows a hacker to trigger a denial-of-service attack.

The vulnerability of the rand function in the Crypt::CBC module of the Perl programming language is related to the use of a insecure program for generating random numbers. Exploiting this vulnerability could allow an attacker to cause a service failure...

CVE-2025-40918: Generation of Predictable Numbers or Identifiers

Authen::SASL::Perl::DIGESTMD5 versions 2.04 through 2.1800 for Perl generates the cnonce insecurely. The cnonce client nonce is generated from an MD5 hash of the PID, the epoch time and the built-in rand function. The PID will come from a small set of numbers, and the epoch time may be guessed, i...

ROS-20250710-05

The vulnerability in the Perl programming language is due to the fact that the software uses the function rand as the default entropy source, which is not cryptographically secure. Exploitation of the vulnerability could allow an attacker to bypass the implemented security restrictions...

CVE-2024-47945

The devices are vulnerable to session hijacking due to insufficient entropy in its session ID generation algorithm. The session IDs are predictable, with only 32,768 possible values per user, which allows attackers to pre-generate valid session IDs, leading to unauthorized access to user sessions...

CVE-2024-56830

The Net::EasyTCP package 0.15 through 0.26 for Perl uses Perl's builtin rand if no strong randomization module is present...

CVE-2021-34430

Eclipse TinyDTLS through 0.9-rc1 relies on the rand function in the C library, which makes it easier for remote attackers to compute the master key and then decrypt DTLS traffic...

CVE-2025-2814 Crypt::CBC versions between 1.21 and 3.05 for Perl may use insecure rand() function for cryptographic functions

Crypt::CBC versions between 1.21 and 3.05 for Perl may use the rand function as the default source of entropy, which is not cryptographically secure, for cryptographic functions. This issue affects operating systems where "/dev/urandom'" is unavailable. In that case, Crypt::CBC will fallback to...

CVE-2025-2814

The Crypt::CBC Perl module (versions 1.21 through 3.05 ) contains a vulnerability where it may use the non-cryptographically secure rand() function as an entropy source for cryptographic functions. This occurs specifically on operating systems where /dev/urandom is unavailable, causing the module...
