Description
ZoneMinder is a free, open source closed-circuit television software application. Prior to 1.38.3, the exportEvents() function concatenates the attacker-controlled exportFile request parameter into a shell command without neutralizing shell metacharacters when an authenticated user with View Events or View Snapshots permission submits an event export request with a crafted exportFile value, a valid CSRF token, and exportDetail enabled. The affected components are exportEvents(), exportFile, web/ajax/event.php, web/skins/classic/includes/export_functions.php. In this attack mechanism, the crafted exportFile value reaches the trailing directory argument of a tar or zip command executed by exec(). The attacker can execute arbitrary operating system commands as the web server user. This issue is fixed in version 1.38.3.

Impact

ZoneMinder’s exportEvents() feature allows an authenticated user with View Events or View Snapshots permission to supply a crafted exportFile value that is concatenated into a shell command without escaping metacharacters. This leads to the execution of arbitrary operating system commands as the web server user, providing full system compromise. The vulnerability is classified under CWE-78, indicating an OS command injection weakness.

Affected Systems

ZoneMinder versions prior to 1.38.3 are affected. The vulnerable components include exportEvents(), exportFile, web/ajax/event.php, and web/skins/classic/includes/export_functions.php.

Risk and Exploitability

With a CVSS score of 8.8, the vulnerability is considered high severity. EPSS data is not available, and the issue is not listed in the CISA KEV catalog. Exploitation requires a valid CSRF token, the exportDetail option enabled, and an authenticated session; thus the attack vector is web‑based through the export feature. A successful exploit would allow an attacker to run arbitrary commands as the web server process.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade ZoneMinder to version 1.38.3 or later, which removes the shell command concatenation bug.
  • If an immediate upgrade is not possible, disable the exportEvents() feature by removing or commenting out the exportFile handling code and disabling exportDetail in the configuration to prevent shell command execution.
  • Restrict user permissions so that only trusted administrators have View Events or View Snapshots access, thereby limiting the number of users who can trigger the export file request.
