CVE-2009-0547

15
FAUCET Score

CVE-2009-0547 describes a vulnerability in Evolution 2.22.3.1 where S/MIME signature verification is performed against an internal copy of the email text, not the version displayed to the user. This allows remote attackers to spoof signatures by altering the user-displayed email content. With a CVSS score of 5.0, this vulnerability has a network attack vector, low complexity, and a potential impact on integrity, as an attacker could deceive users about the authenticity of an email. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion, and it is not listed in the KEV catalog.
