AI-suggested
- Immediately upgrade LimeSurvey to the latest version once an official patch addressing CVE-2024-42902 is released.
- Until patches are available, restrict access to the js_localize.php endpoint via web application firewalls (WAFs) or network access controls, limiting it to trusted IP addresses or internal networks only.
- Implement input validation and sanitization at the web server or application firewall level to block suspicious payloads targeting the 'lng' parameter.
- Monitor web server logs for unusual or repeated requests to js_localize.php containing suspicious or malformed 'lng' parameters.
- Employ runtime application self-protection (RASP) tools if available to detect and block code injection attempts in real time.
- Conduct thorough security audits and penetration testing focusing on LimeSurvey installations to identify any signs of compromise or exploitation attempts.
- Educate system administrators and developers about this vulnerability to ensure prompt response and remediation.
- Consider isolating LimeSurvey instances in segmented network zones to limit lateral movement in case of compromise.
Description
An issue in the js_localize.php function of LimeSurvey v6.6.2 and before allows attackers to execute arbitrary code via injecting a crafted payload into the lng parameter of the js_localize.php function
