12
FAUCET Score

CVE-2013-5679 describes a vulnerability in the OWASP Enterprise Security API (ESAPI) for Java 2.x before version 2.1.0, where the authenticated-encryption feature fails to properly resist tampering with serialized ciphertext. This flaw, categorized as CWE-310, allows remote attackers to bypass cryptographic protections due to a null MAC and zero MAC length in the default configuration. The vulnerability has a low CVSS score of 2.6, indicating a local attack vector with high complexity and limited impact (partial confidentiality and integrity). There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage, suggesting it is not a widely targeted or discussed vulnerability.
