CVE-2024-0320: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in FireEye FireEye Malware Analysis (AX)
Cross-Site Scripting in FireEye Malware Analysis (AX) affecting version 9.0.3.936530. This vulnerability allows an attacker to send a specially crafted JavaScript payload in the application URL to retrieve the session details of a legitimate user.
AI Analysis
Technical Summary
CVE-2024-0320 is a Cross-Site Scripting (XSS) vulnerability identified in FireEye Malware Analysis (AX) version 9.0.3.936530. This vulnerability arises from improper neutralization of input during web page generation, specifically allowing an attacker to inject malicious JavaScript payloads via the application URL. When a legitimate user accesses a crafted URL containing the malicious script, the script executes in the context of the user's browser session. This can lead to the attacker retrieving session details, potentially enabling session hijacking or unauthorized actions within the affected application. The vulnerability is classified under CWE-79, which pertains to improper input sanitization leading to XSS attacks. According to the CVSS 3.1 scoring, it has a score of 5.4 (medium severity), with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), requires user interaction (UI:R), scope unchanged (S:U), and impacts confidentiality and integrity to a low degree (C:L/I:L), with no impact on availability (A:N). No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability allows attackers to steal session information by tricking users into clicking malicious URLs, which could lead to unauthorized access or manipulation of the FireEye Malware Analysis (AX) environment.
Potential Impact
For European organizations using FireEye Malware Analysis (AX) version 9.0.3.936530, this vulnerability poses a risk of session hijacking and unauthorized access to sensitive malware analysis data. Given that FireEye products are widely used in cybersecurity operations, exploitation could undermine the integrity of malware analysis results, potentially leading to incorrect threat assessments or exposure of sensitive internal security data. While the vulnerability requires user interaction, targeted phishing or social engineering campaigns could be effective vectors. The medium severity rating indicates moderate risk; however, in environments where FireEye Malware Analysis is critical for incident response or threat intelligence, even limited unauthorized access could have significant operational impacts. Confidentiality and integrity of session data are at risk, which could facilitate lateral movement or privilege escalation if combined with other vulnerabilities or misconfigurations. The lack of known exploits suggests limited immediate threat but does not preclude future exploitation, especially as attackers often develop exploits post-disclosure.
Mitigation Recommendations
European organizations should implement several specific mitigations beyond generic advice: 1) Immediately audit and monitor all FireEye Malware Analysis (AX) instances for unusual URL access patterns or suspicious user activity that could indicate attempted exploitation. 2) Educate users with access to the system about the risks of clicking unsolicited or suspicious links, emphasizing the importance of verifying URLs before access. 3) Employ web application firewalls (WAFs) with custom rules to detect and block malicious JavaScript payloads in URLs targeting FireEye Malware Analysis interfaces. 4) Restrict access to the FireEye Malware Analysis web interface to trusted networks or VPNs to reduce exposure to external attackers. 5) Implement strict Content Security Policy (CSP) headers on the application to limit the execution of unauthorized scripts. 6) Regularly update and patch FireEye products as vendor updates become available, and engage with FireEye support to obtain any interim fixes or workarounds. 7) Consider session management enhancements such as shorter session timeouts and multi-factor authentication to reduce the impact of stolen session tokens.
