CVE-2024-41705 is a stored cross-site scripting (XSS) vulnerability identified in the Archer Platform, a governance, risk, and compliance (GRC) software solution widely used by enterprises and government agencies. The vulnerability exists in versions prior to 2024.06, including 6.13.0.4 and 6.14.0.4, which contain fixes. The flaw allows a remote authenticated user with low privileges to inject malicious HTML or JavaScript code into the application’s trusted data store. This malicious code is then served to other users when they access the compromised data through their web browsers, causing the browser to execute the injected script within the security context of the Archer application. This can lead to unauthorized disclosure of sensitive information, session hijacking, or manipulation of application data. The vulnerability does not require user interaction beyond accessing the affected data, but it does require the attacker to have valid credentials with at least low-level privileges. The CVSS 3.1 base score is 7.1, reflecting high severity due to the high impact on confidentiality and integrity, low attack complexity, and limited privileges required. Although no active exploits have been reported, the vulnerability’s nature and the criticality of the Archer Platform in risk management environments make it a significant threat. The issue is related to CWE-79 (Improper Neutralization of Input During Web Page Generation), a common vector for XSS attacks. Organizations should prioritize patching to the fixed versions 6.13.0.4 or 6.14.0.4 or later to prevent exploitation.

The impact of CVE-2024-41705 is substantial for organizations using the Archer Platform, as it enables an authenticated attacker to execute arbitrary scripts in the context of the application. This can lead to unauthorized access to sensitive governance, risk, and compliance data, potentially exposing confidential business or regulatory information. Attackers could hijack user sessions, manipulate data, or perform actions on behalf of legitimate users, undermining data integrity and trust in the platform. Since Archer is often used by large enterprises and government entities to manage critical compliance and risk data, exploitation could disrupt compliance reporting, risk assessments, and decision-making processes. The requirement for authentication limits exposure somewhat but does not eliminate risk, especially in environments with many users or weak credential management. The vulnerability could also be leveraged as a foothold for further attacks within the network. Overall, the threat poses a high risk to confidentiality and integrity, with no direct impact on availability reported.

To mitigate CVE-2024-41705, organizations should immediately upgrade affected Archer Platform instances to versions 6.13.0.4, 6.14.0.4, or later where the vulnerability is patched. In environments where immediate patching is not feasible, implement strict access controls to limit the number of users with write permissions to the data stores vulnerable to injection. Conduct thorough input validation and output encoding on all user-supplied data fields to prevent malicious script injection. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts within the application context. Monitor logs for unusual activity indicative of attempted XSS exploitation, such as unexpected script tags or anomalous user behavior. Educate users about the risks of stored XSS and encourage reporting of suspicious application behavior. Additionally, review and tighten authentication and session management controls to reduce the risk of session hijacking. Regularly audit and test the application for XSS and other injection vulnerabilities as part of a secure development lifecycle.
