CVE-2024-58278 is an OS command injection vulnerability classified under CWE-78, affecting IndigoSTAR Software's perl2exe tool up to version 30.10C. The vulnerability arises because the software improperly neutralizes special elements used in OS commands, allowing an attacker with local authenticated access to manipulate the 0th argument of packed executables. This manipulation enables the execution of arbitrary executables or scripts, effectively bypassing any restrictions that would normally prevent such execution. The flaw allows attackers to gain unauthorized access and execute malicious code with the privileges of the user running the perl2exe-packed executable. The vulnerability does not require user interaction but does require local authentication, meaning the attacker must already have some level of access to the system. The CVSS 4.0 score of 8.5 reflects the high impact on confidentiality, integrity, and availability, with low attack complexity and no need for user interaction. No public exploits have been reported yet, but the potential for abuse is significant, especially in environments where perl2exe is used to distribute Perl applications. The lack of available patches at the time of publication increases the urgency for mitigation through access control and monitoring.

For European organizations, this vulnerability poses a significant risk, particularly for those in software development, IT services, and industries relying on Perl applications packaged with perl2exe. Successful exploitation can lead to arbitrary code execution, allowing attackers to compromise system confidentiality by accessing sensitive data, integrity by modifying or injecting malicious code, and availability by disrupting services or causing system failures. Since exploitation requires local authenticated access, insider threats or attackers who have gained initial footholds can escalate privileges or move laterally within networks. The high CVSS score indicates a severe impact, and the absence of public exploits does not diminish the risk, as attackers may develop exploits rapidly. Organizations with lax local access controls or insufficient monitoring are especially vulnerable. The threat could affect critical infrastructure, software vendors, and enterprises using perl2exe in their development pipelines or deployment processes.

1. Restrict local access to systems running perl2exe-packed executables to trusted users only, enforcing strict authentication and authorization controls. 2. Monitor execution of packed executables for unusual behavior, such as unexpected invocation of other executables or scripts, using endpoint detection and response (EDR) tools. 3. Implement application whitelisting to prevent unauthorized executables from running. 4. Isolate development and deployment environments to limit exposure of vulnerable perl2exe versions. 5. Regularly audit systems for presence of perl2exe and identify versions in use. 6. Engage with IndigoSTAR Software for updates and apply patches promptly once released. 7. Educate local users about the risks of executing untrusted packed executables. 8. Employ intrusion detection systems (IDS) tuned to detect command injection patterns. 9. Use privilege separation and least privilege principles to limit the impact of potential exploitation. 10. Prepare incident response plans specifically addressing local privilege escalation and code execution scenarios.
