Apache MINA Deserialization RCE Vulnerability

CVSS 10.0 CriticalCriticalEPSS 0.25 · 97th percentile

Critical, because:

  • CVSS score 10.0: 9.0 or more.
  • CVSS score 10.0 (7.0 or more) and EPSS 0.25 (0.1 or more): a high score and a real chance of exploitation in the next 30 days.

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Apache MINA core (org.apache.mina:mina-core) versions 2.0.0-M1 before 2.0.27, 2.1.0 before 2.1.10, and 2.2.0 before 2.2.4 are vulnerable to unsafe Java deserialization in ObjectSerializationDecoder. An attacker who can send crafted serialized data to an affected application that uses ObjectSerializationCodecFactory can potentially execute remote code. Upgrade to mina-core 2.0.27, 2.1.10, or 2.2.4 or later, and also explicitly allow the classes the decoder should accept, since the upgrade alone is not sufficient.
