AI-suggested
To mitigate this vulnerability, organizations should immediately upgrade IPFire installations to version 2.29 (Core Update 198) or later, where the issue is patched. If upgrading is not immediately feasible, restrict access to the Proxy report generation interface to trusted administrators only, ideally via VPN or secure management networks. Implement network-level access controls and monitoring to detect unusual POST requests to /cgi-bin/logs.cgi/calamaris.dat. Apply strict input validation and sanitization on all parameters used in shell commands, ensuring that special characters and shell metacharacters are properly escaped or rejected. Consider running the mkreport helper with even more restricted privileges or within a sandboxed environment to limit potential damage. Regularly audit firewall logs and system behavior for signs of exploitation attempts. Additionally, educate administrators about the risks of command injection vulnerabilities and the importance of applying security updates promptly. Employ intrusion detection systems (IDS) tuned to detect anomalous command injection patterns targeting IPFire components.
Description
IPFire versions prior to 2.29 (Core Update 198) contain a command injection vulnerability that allows an authenticated attacker to execute arbitrary commands as the user 'nobody' via multiple parameters when creating a Proxy report. When a user creates a Proxy report the application issues an HTTP POST to /cgi-bin/logs.cgi/calamaris.dat and reads the values of DAY_BEGIN, MONTH_BEGIN, YEAR_BEGIN, DAY_END, MONTH_END, YEAR_END, NUM_DOMAINS, PERF_INTERVAL, NUM_CONTENT, HIST_LEVEL, NUM_HOSTS, NUM_URLS, and BYTE_UNIT, which are interpolated directly into the shell invocation of the mkreport helper. Because these parameters are never sanitized for improper characters or constructs, a crafted POST can inject shell metacharacters into one or more fields, causing arbitrary commands to run with the privileges of the 'nobody' user.
