CVE-2024-52762 is a cross-site scripting (XSS) vulnerability affecting Ganglia-web versions 3.73 through 3.76, located in the /master/header.php component. The vulnerability arises from improper sanitization of the 'tz' parameter, which is used to specify timezone information. An attacker with at least limited privileges (PR:L) can craft a malicious payload injected into this parameter, which is then reflected in the web interface without adequate encoding or filtering. This allows execution of arbitrary JavaScript or HTML in the context of the victim's browser session. The vulnerability requires user interaction (UI:R), such as tricking a user into clicking a crafted URL or visiting a malicious page that includes the payload. The CVSS vector indicates network attack vector (AV:N), low attack complexity (AC:L), partial confidentiality and integrity impact (C:L/I:L), no availability impact (A:N), and scope change (S:C), meaning the vulnerability can affect resources beyond the initially vulnerable component. Although no public exploits are currently known, the vulnerability poses a risk of session hijacking, credential theft, or unauthorized actions performed on behalf of the victim user. Ganglia-web is a widely used monitoring tool in high-performance computing clusters, research institutions, and enterprise environments, making this vulnerability relevant to organizations relying on it for system monitoring and management. The absence of official patches at the time of publication necessitates immediate attention to mitigation strategies.

The primary impact of CVE-2024-52762 is the potential compromise of confidentiality and integrity within affected Ganglia-web environments. Successful exploitation can lead to theft of session cookies, enabling attackers to impersonate legitimate users and potentially escalate privileges or access sensitive monitoring data. Malicious scripts could also alter the displayed information or perform unauthorized actions within the web interface, undermining trust in monitoring data. While availability is not directly affected, the indirect consequences of compromised monitoring integrity could lead to delayed detection of system issues or misinformed operational decisions. Organizations relying on Ganglia-web for critical infrastructure monitoring, especially in research, academic, and enterprise HPC clusters, may face increased risk of targeted attacks or lateral movement within their networks. The requirement for user interaction and limited privileges reduces the likelihood of widespread automated exploitation but does not eliminate targeted attack risks. The medium CVSS score reflects these factors, indicating a moderate but meaningful threat to affected systems.

To mitigate CVE-2024-52762 effectively, organizations should: 1) Immediately restrict access to the Ganglia-web interface to trusted users and networks, employing network segmentation and firewall rules to limit exposure. 2) Educate users about the risks of clicking untrusted links or opening suspicious URLs that could exploit the 'tz' parameter. 3) Implement web application firewall (WAF) rules to detect and block suspicious payloads targeting the 'tz' parameter, focusing on common XSS attack patterns. 4) Monitor web server and application logs for unusual requests containing suspicious 'tz' parameter values indicative of attempted exploitation. 5) If possible, apply input validation and output encoding patches or workarounds, such as sanitizing the 'tz' parameter on the server side or disabling timezone customization features temporarily. 6) Engage with the Ganglia community or vendors for official patches or updates addressing this vulnerability and plan timely deployment once available. 7) Conduct internal penetration testing or code review to identify similar injection points in the application. 8) Consider deploying Content Security Policy (CSP) headers to reduce the impact of potential XSS attacks by restricting script execution sources. These targeted steps go beyond generic advice by focusing on the specific vulnerable parameter and the operational context of Ganglia-web.
