7.5.1
CVE-2023-52332 is a directory traversal vulnerability discovered in Allegra, allowing attackers to potentially disclose sensitive information. This flaw stems from inadequate validation of user-supplied paths within the serveMathJaxLibraries method, enabling unauthorized file access. The vulnerability affects Allegra versions 7.5.0 build 29 and earlier, and a fix is available in version 7.5.1.
The core of this vulnerability lies in the serveMathJaxLibraries method, which fails to properly validate user-supplied paths before using them in file operations. This lack of validation allows an attacker to craft malicious requests that bypass security controls and access arbitrary files on the server. Successful exploitation could lead to the disclosure of sensitive data such as configuration files, database credentials, or other confidential information. The potential for lateral movement is significant if an attacker gains access to credentials, enabling them to compromise other systems within the network. The blast radius extends to any system or data accessible from the compromised Allegra instance.
This vulnerability was reported to ZDI (ZDI-CAN-22532) and subsequently disclosed publicly. While no active exploitation campaigns have been definitively linked to this CVE, the ease of exploitation and potential impact warrant careful attention. The vulnerability's severity is considered HIGH due to the potential for information disclosure and subsequent compromise. Public proof-of-concept exploits are likely to emerge, increasing the risk of exploitation.
Organizations using Allegra versions 7.5.0 build 29 and earlier, particularly those hosting Allegra on publicly accessible servers or shared hosting environments, are at significant risk. Systems with weak file permissions or inadequate access controls are also more vulnerable.

The primary mitigation for CVE-2023-52332 is to upgrade Allegra to version 7.5.1 or later, which includes the necessary fix for the path validation issue. If upgrading immediately is not feasible, consider implementing temporary workarounds such as restricting access to the serveMathJaxLibraries endpoint or implementing stricter file access controls on the server. Review and harden file permissions to limit the potential impact of a successful attack. After upgrading, confirm the fix by attempting to access files outside of the intended directory via the serveMathJaxLibraries endpoint; access should be denied.
