CVE-2006-3204

15
FAUCET Score

CVE-2006-3204 describes a cryptographic weakness in Ultimate PHP Board (UPB) versions 1.9.6 and earlier. The vulnerability stems from its use of a weak block cipher with a large key collision space, allowing remote attackers to derive the decryption key. This is achieved by intercepting the plaintext password during login and the corresponding ciphertext from the "pass_env" cookie. The vulnerability has a CVSS score of 5.0, indicating a medium severity. It is easily exploitable over the network with low attack complexity, potentially leading to unauthorized information disclosure (confidentiality impact). There is no impact on integrity or availability. There is no evidence of active exploitation, nor are there known Metasploit modules, Nuclei templates, or ExploitDB entries for this CVE. Community discussion and media coverage are minimal, suggesting low public attention.
