Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) vulnerability in Apache StreamPipes user self-registration and password recovery mechanism. This allows an attacker to guess the recovery token in a reasonable time and thereby to take over the attacked users account. This issue affects Apache StreamPipes: from 0.69.0 through 0.93.0.
Users are recommended to upgrade to version 0.95.0, which fixes the issue.
The product uses a Pseudo-Random Number Generator (PRNG) in a security context, but the PRNG’s algorithm is not cryptographically strong.
When a non-cryptographic PRNG is used in a cryptographic context, it can expose the cryptography to certain types of attacks. Often a pseudo-random number generator (PRNG) is not designed for cryptography. Sometimes a mediocre source of randomness is sufficient or preferable for algorithms that use random numbers. Weak generators generally take less processing power and/or do not use the precious, finite, entropy sources on a system. While such PRNGs might have very useful features, these same features could be used to break the cryptography.
