CVE-2024-52532 is a vulnerability identified in GNOME libsoup, a widely used HTTP client/server library for GNOME applications, specifically affecting versions prior to 3.6.1. The flaw arises during the processing of certain WebSocket data patterns sent by clients, which triggers an infinite loop within the library's code. This infinite loop leads to uncontrolled memory consumption, potentially exhausting system resources and causing denial of service (DoS). The vulnerability is exploitable remotely over the network without requiring any privileges or user interaction, making it particularly dangerous in exposed environments. The CVSS v3.1 score of 7.5 reflects a high severity level, emphasizing the impact on availability (A:H) while confidentiality and integrity remain unaffected. The underlying weakness corresponds to CWE-835 (Loop with Unreachable Exit Condition), indicating a logic flaw in loop termination conditions. Although no public exploits have been reported yet, the vulnerability's characteristics suggest it could be leveraged by attackers to disrupt services relying on libsoup, including GNOME desktop applications and backend services that utilize this library for WebSocket communication. The absence of a patch link indicates that a fix may be pending or newly released, so organizations should monitor vendor advisories closely.

For European organizations, the primary impact of CVE-2024-52532 is the potential for denial of service attacks against systems using vulnerable versions of GNOME libsoup. This can lead to service outages, degraded performance, and increased operational costs due to system instability or crashes. Organizations relying on GNOME-based desktop environments or server applications that handle WebSocket connections are at risk. Critical infrastructure, public sector services, and enterprises with Linux-based deployments could experience disruptions, affecting business continuity and user trust. Since the vulnerability does not compromise confidentiality or integrity, data breaches are unlikely; however, availability impacts can have cascading effects on dependent services and users. The ease of remote exploitation without authentication increases the threat landscape, especially for internet-facing applications or internal networks where malicious actors may gain access. European entities with high adoption of open-source GNOME technologies, particularly in countries with strong Linux user bases, face a higher likelihood of encountering this threat.

To mitigate CVE-2024-52532, European organizations should prioritize upgrading GNOME libsoup to version 3.6.1 or later as soon as the patch is available. Until then, applying temporary workarounds such as disabling or restricting WebSocket functionality in affected applications can reduce exposure. Network-level defenses should be enhanced by implementing WebSocket traffic filtering and anomaly detection to identify and block malformed or suspicious data patterns that could trigger the infinite loop. Employing rate limiting and connection throttling on WebSocket endpoints can also help mitigate resource exhaustion. Regular monitoring of system resource usage and application logs will aid in early detection of exploitation attempts. Security teams should coordinate with software vendors and open-source communities to track patch releases and advisories. Additionally, conducting vulnerability scans and penetration tests focusing on WebSocket implementations can identify vulnerable instances. Finally, educating developers and system administrators about safe WebSocket handling practices will reduce the risk of similar vulnerabilities in the future.
