CVE-2024-7740 is a critical server-side request forgery (SSRF) vulnerability discovered in ltcms versions 1.0.20–1.0.20. This flaw allows attackers to manipulate internal requests, potentially exposing sensitive data or gaining unauthorized access. The vulnerability resides in the /api/test/download endpoint and has been publicly disclosed. A fix is available in version 1.0.21.
The SSRF vulnerability in ltcms allows an attacker to craft malicious requests through the /api/test/download endpoint. By manipulating the 'url' parameter, an attacker can force the server to make requests to arbitrary internal or external resources. This could lead to the exposure of sensitive data stored within the internal network, such as configuration files, database credentials, or internal API endpoints. Furthermore, an attacker could potentially use this vulnerability to scan the internal network for other vulnerable services or to perform actions on behalf of the server, escalating their privileges. The public disclosure and availability of an exploit significantly increase the risk of exploitation.
CVE-2024-7740 has been publicly disclosed, and a proof-of-concept exploit is available, indicating a high probability of exploitation. The vulnerability was reported on 2024-08-13. The vendor was contacted but did not respond. This lack of response increases the urgency to apply the patch or implement mitigating controls. The vulnerability is not currently listed on CISA KEV as of this writing.

The primary mitigation for CVE-2024-7740 is to upgrade ltcms to version 1.0.21 or later, which contains the fix for this vulnerability. If upgrading is not immediately feasible, consider implementing temporary workarounds such as restricting outbound network access from the ltcms server to only necessary destinations. Implement strict input validation on the 'url' parameter in the /api/test/download endpoint to prevent malicious input. Web application firewalls (WAFs) configured to detect and block SSRF attempts can also provide a layer of protection. Monitor ltcms logs for suspicious outbound requests originating from the /api/test/download endpoint.
Update to a patched version or contact the vendor for a solution. As no patched version is available, it is recommended to disable or restrict access to the /api/test/download endpoint until an update is released. Monitor network traffic for potential exploitation attempts.
