Detailsinfo

A vulnerability was found in IPFire up to 2.28. It has been declared as critical. Affected by this vulnerability is an unknown functionality of the file /cgi-bin/logs.cgi/calamaris.dat of the component POST Handler. The manipulation of the argument DAY_BEGIN/MONTH_BEGIN/YEAR_BEGIN/DAY_END/MONTH_END/YEAR_END/NUM_DOMAINS/PERF_INTERVAL/NUM_CONTENT/HIST_LEVEL/NUM_HOSTS/NUM_URLS/BYTE_UNIT with an unknown input leads to a os command injection vulnerability. The CWE definition for the vulnerability is CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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.

The weakness was shared by Alex Williams. The advisory is shared at ipfire.org. This vulnerability is known as CVE-2025-34311 since 04/15/2025. The exploitation appears to be easy. The attack can be launched remotely. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1202 for this issue.

Upgrading to version 2.29 eliminates this vulnerability.
