CVE-2026-5083

CVE-2026-5083 affects the Perl module Ado::Sessions up to version 0.935. The vulnerability stems from generating session IDs with a SHA-1 hash seeded by the built-in rand() function, the epoch time, and the PID. The PID comes from a small set of numbers, and the epoch time may be guessed if not l...

PT-2026-31087

Amon2::Plugin::Web::CSRFDefender versions from 7.00 through 7.03 for Perl generate an insecure session id. The generate session id function will attempt to read bytes from the /dev/urandom device, but if that is unavailable then it generates bytes using SHA-1 hash seeded with the built-in rand...

CVE-2026-5420

A security flaw has been discovered in Shinrays Games Goods Triple App up to 1.200. The affected element is an unknown function of the file jRwTX.java of the component cats.goods.sort.sorting.games. Performing a manipulation of the argument AESIV/AESPASSWORD results in use of hard-coded...

EUVD-2025-209143

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...

CVE-2025-15618

CVE-2025-15618 affects Perl module Business::OnlinePayment::StoredTransaction up to version 0.01. The root cause is generating a secret key for encrypting credit card data by taking an MD5 hash of a single rand() call, which is not cryptographically secure. Consequence: high impact on confidentia...

CVE-2025-15604

Summary (CVE-2025-15604) Amon2 for Perl with vulnerable random_string implementation affects versions before 6.17. In 6.06–6.16, random_string reads /dev/urandom if available; if not, it falls back to a SHA-1 hash seeded with rand(), the PID, and the high-resolution epoch time. The epoch time can...

Security Bulletin: IBM Sterling B2B Integrator and IBM Sterling File Gateway are Vulnerable due to Cryptographic Weakness in IBM Liberty Server ( CVE-2020-36732)

Summary IBM Sterling B2B Integrator and IBM Sterling File Gateway have addressed the cryptographic weakness vulnerability Vulnerability Details CVEID:CVE-2020-36732 DESCRIPTION: The crypto-js package before 3.2.1 for Node.js generates random numbers by concatenating the string "0." with an intege...

SUSE CVE-2025-40926

Plack::Middleware::Session::Simple versions before 0.05 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...
