AI-suggested
Users should upgrade Apache TomEE to version 10.3.0 or 11.0.0-M2, where the vulnerability is fixed by using a cryptographically secure random number generator for session identifiers. No other mitigation is indicated by the vendor advisory.
Description
Apache TomEE versions prior to 10.3.0 and 11.0.0-M2 use a non-cryptographic pseudo-random number generator (PRNG) to generate HTTP session identifiers by default. This weakness allows a remote attacker who observes a session identifier to predict other session identifiers, potentially hijacking user sessions if HTTP sessions are used for authentication. The issue is fixed in versions 10.3.0 and 11.0.0-M2.
