CVE-2024-49211 in Archer
Summary
by MITRE • 10/22/2024
Reflected XSS was discovered in a Dashboard Listing Archer Platform UX page in Archer Platform 6.x before version 2024.08. A remote unauthenticated attacker could potentially exploit this by tricking a victim application user into supplying malicious HTML or JavaScript code to the vulnerable web application; the malicious code is then reflected back to the victim and executed by the web browser in the context of the vulnerable web application.

The vulnerability identified as CVE-2024-49211 represents a critical reflected cross-site scripting flaw within the Archer Platform 6.x dashboard listing interface. This security weakness exists in the user experience layer of the Archer Platform, specifically affecting versions prior to the 2024.08 release. The vulnerability stems from inadequate input validation and output encoding mechanisms within the web application's handling of user-supplied parameters. Attackers can exploit this weakness by crafting malicious payloads that are then reflected back to unsuspecting users through the vulnerable dashboard page, creating a persistent security risk for organizations utilizing affected versions of the platform.
The technical exploitation of this reflected XSS vulnerability follows a classic attack pattern where an unauthenticated remote attacker crafts malicious input that gets processed by the web application and subsequently reflected in the HTTP response to the victim user. The Archer Platform's UX page fails to properly sanitize or encode user input parameters before rendering them in the web page context, allowing malicious JavaScript code to execute within the victim's browser session. This occurs because the application does not implement proper content security policies or input validation controls that would prevent the execution of unauthorized code. The vulnerability specifically affects the dashboard listing functionality, making it particularly dangerous as it targets the primary interface through which users interact with the platform's administrative features.
The operational impact of this vulnerability extends beyond simple script execution, as it enables attackers to perform a range of malicious activities including session hijacking, credential theft, and data exfiltration from authenticated users. An attacker could potentially leverage this vulnerability to escalate privileges, access sensitive organizational data, or redirect users to malicious websites that could further compromise their systems. The reflected nature of the vulnerability means that attacks can be delivered through various vectors including phishing emails, compromised web links, or social engineering campaigns that trick users into clicking malicious URLs. This makes the attack surface particularly broad and difficult to defend against, as users must be vigilant about every link they click within the Archer Platform environment.
Organizations should immediately implement comprehensive mitigations including updating to Archer Platform version 2024.08 or later, which contains the necessary patches to address the reflected XSS vulnerability. Additionally, implementing robust input validation and output encoding mechanisms at the application level can provide defense-in-depth protection against similar vulnerabilities. Network-level protections such as web application firewalls should be configured to detect and block suspicious input patterns that could indicate XSS attack attempts. The vulnerability aligns with CWE-79 which specifically addresses cross-site scripting flaws in web applications, and represents a clear violation of secure coding practices recommended by the OWASP Top Ten Project. From an ATT&CK framework perspective, this vulnerability maps to T1566.001 (Phishing) and T1059.007 (Scripting) techniques, as attackers can leverage it to deliver malicious payloads through social engineering and execute code within user browser contexts. Regular security assessments and penetration testing should be conducted to identify similar vulnerabilities in other components of the Archer Platform ecosystem.
