CVE-2009-0582

18
FAUCET Score

CVE-2009-0582 describes a vulnerability in the NTLM SASL authentication mechanism within Evolution Data Server (versions 2.24.5 and earlier, and 2.25.92 and earlier 2.25.x versions). The flaw stems from insufficient validation of length values in NTLM challenge packets, allowing remote mail servers to potentially read client process memory or cause a denial of service (client crash). This vulnerability has a CVSS score of 5.8, indicating a medium severity. It can be exploited remotely with medium attack complexity and does not require authentication, potentially leading to partial confidentiality impact (information disclosure) and partial availability impact (denial of service). There is no evidence of active exploitation, and no public exploit code (Metasploit, Nuclei, ExploitDB) is available. Community discussion and media coverage for this CVE are minimal, suggesting low public attention.
