24
FAUCET Score

CVE-2024-33535 is an unauthenticated local file inclusion (LFI) vulnerability affecting Zimbra Collaboration (ZCS) versions 9.0 and 10.0, specifically in the handling of the 'packages' parameter. This high-severity flaw (CVSS 7.5) allows attackers to read arbitrary local files within a specific directory without authentication, posing a significant risk of unauthorized information disclosure. While no public exploits, Metasploit modules, or Nuclei templates are currently available, and there is minimal community discussion, organizations using affected Zimbra versions should prioritize patching to mitigate potential risks.
