CVE-2024-49210 is a reflected Cross-Site Scripting (XSS) vulnerability identified in the iView List Archer Platform UX page within Archer Platform versions 6.x before 2024.09. Reflected XSS occurs when malicious input sent by an attacker is immediately reflected by the web application in the response without proper sanitization or encoding, causing the victim's browser to execute the injected script. In this case, a remote attacker who does not need to authenticate can craft a malicious URL or input containing HTML or JavaScript code. When a legitimate user accesses this crafted input, the malicious code executes in their browser under the security context of the Archer Platform application. This can lead to theft of sensitive information such as session cookies, user credentials, or other confidential data, and potentially allow limited manipulation of the victim's interaction with the application. The vulnerability is classified under CWE-79, which covers improper neutralization of input during web page generation. The CVSS 3.1 base score is 5.2, reflecting medium severity, with attack vector network, low attack complexity, no privileges required, but requiring user interaction. The impact is high on confidentiality, low on integrity, and no impact on availability. No known exploits have been reported in the wild, and no official patches have been linked at the time of publication. The vulnerability affects Archer Platform 6.x versions prior to 2024.09, a widely used governance, risk, and compliance (GRC) solution by RSA. Given the nature of reflected XSS, exploitation depends on social engineering to trick users into clicking malicious links or submitting crafted inputs. The vulnerability's scope is limited to users of the affected Archer Platform instances. Organizations relying on Archer Platform for critical risk management and compliance functions should prioritize remediation once patches are available.

The primary impact of CVE-2024-49210 is on the confidentiality of data handled by the Archer Platform, as successful exploitation can lead to theft of session tokens, user credentials, or other sensitive information accessible within the victim's browser session. This could enable attackers to impersonate users or escalate privileges indirectly. The integrity impact is low but present, as attackers might manipulate client-side interactions or inject misleading content. Availability is not affected. Since the vulnerability is reflected XSS, exploitation requires user interaction, typically through social engineering techniques such as phishing emails containing malicious links. The scope is limited to users who access the vulnerable Archer Platform web interface. Organizations worldwide using Archer Platform 6.x for governance, risk, and compliance management could face targeted attacks aiming to compromise user sessions or harvest sensitive data. This may lead to regulatory compliance failures, data breaches, and erosion of trust in critical risk management systems. Although no known exploits are currently reported, the medium severity score and the widespread use of Archer Platform in enterprise environments underscore the importance of timely mitigation.

1. Monitor RSA Archer Platform vendor communications closely and apply official patches or updates as soon as they become available for versions prior to 2024.09. 2. Implement strict input validation and output encoding on all user-supplied data within the Archer Platform, especially on the iView List UX pages, to prevent injection of malicious scripts. 3. Deploy Content Security Policy (CSP) headers to restrict the execution of untrusted scripts and reduce the impact of potential XSS attacks. 4. Educate users on the risks of clicking unsolicited links and implement phishing awareness training to reduce the likelihood of successful social engineering. 5. Use web application firewalls (WAFs) with rules designed to detect and block reflected XSS attack patterns targeting the Archer Platform. 6. Conduct regular security assessments and penetration testing focused on web application vulnerabilities to identify and remediate similar issues proactively. 7. Restrict access to Archer Platform interfaces to trusted networks or VPNs where feasible to reduce exposure to unauthenticated attackers. 8. Review and harden session management controls to limit the impact of stolen session tokens, including short session lifetimes and multi-factor authentication where supported.
