CVE-2024-25081 is a command injection vulnerability identified in the Splinefont component of FontForge, an open-source font editor widely used for creating and modifying font files. The vulnerability arises from improper handling of crafted filenames, which can be manipulated to execute arbitrary commands on the host system. Specifically, when a maliciously crafted filename is processed, it can trigger command injection (CWE-77), allowing an attacker to execute system-level commands. The CVSS 3.1 base score is 4.2, reflecting a medium severity level. The attack vector is local (AV:L), requiring the attacker to have low privileges (PR:L) and necessitating user interaction (UI:R), such as opening or importing a malicious font file. The attack complexity is high (AC:H), indicating that exploitation is not straightforward and requires specific conditions. The impact on confidentiality, integrity, and availability is limited (C:L/I:L/A:L), meaning that while some data or system integrity could be compromised, the overall damage is constrained. No patches or fixes have been published yet, and no known exploits are reported in the wild, suggesting that the vulnerability is newly disclosed and not yet actively exploited. The vulnerability affects all versions of FontForge up to the date of disclosure (through 20230101).

For European organizations, the impact of CVE-2024-25081 depends largely on the usage of FontForge within their environments. Organizations involved in graphic design, publishing, typography, and software development that utilize FontForge for font manipulation are at risk if attackers gain local access to their systems. Successful exploitation could lead to unauthorized command execution, potentially allowing attackers to escalate privileges, manipulate files, or disrupt services. However, since exploitation requires local access and user interaction, remote attacks are unlikely, limiting the threat surface. Confidentiality and integrity of data related to font files and possibly other system components could be compromised. Availability impact is limited but could include denial of service if critical processes are disrupted. The lack of known exploits reduces immediate risk, but organizations should remain vigilant, especially those with open or shared workstations where malicious font files might be introduced.

To mitigate CVE-2024-25081, European organizations should implement several specific measures beyond generic advice: 1) Restrict FontForge usage to trusted users and systems, minimizing exposure to untrusted font files. 2) Enforce strict input validation and sanitization on filenames before processing within FontForge or any related workflows. 3) Employ application whitelisting and sandboxing techniques to limit the execution scope of FontForge and contain potential command injection attempts. 4) Monitor local system logs and user activities for unusual command executions or file handling behaviors related to font files. 5) Educate users about the risks of opening font files from untrusted sources and encourage verification of file origins. 6) Maintain up-to-date backups of critical data to recover from potential integrity or availability impacts. 7) Track FontForge updates and apply patches promptly once available. 8) Consider using alternative font editing tools with a stronger security track record if feasible.
