CVE-2024-4853 identifies a memory handling vulnerability classified under CWE-762 (Mismatched Memory Management Routines) in the Wireshark Foundation's editcap utility, which is used for editing and manipulating capture files. The flaw arises from improper management of memory allocation and deallocation routines, which can lead to undefined behavior such as application crashes. Specifically, when editcap processes a specially crafted capture file, the mismatched memory operations can cause a denial of service by crashing the utility. The vulnerability affects versions 3.6.0, 4.0.0, and 4.2.0 of editcap. The CVSS 3.1 score is 3.6 (low severity), reflecting that exploitation requires local access (AV:L), high attack complexity (AC:H), no privileges (PR:N), and user interaction (UI:R). The impact is limited to availability, with no confidentiality or integrity loss. No known public exploits or patches are available as of the publication date (May 14, 2024). Given editcap's role in network capture file processing, this vulnerability could be triggered by opening or manipulating malicious capture files, potentially disrupting workflows that rely on this tool.

For European organizations, the primary impact of CVE-2024-4853 is the potential for denial of service affecting network analysis and forensic workflows that utilize editcap. This could disrupt incident response, network troubleshooting, and security monitoring activities, especially in environments where editcap is integrated into automated pipelines or used frequently by security teams. Although the vulnerability does not allow for data breach or code execution, the loss of availability could delay detection and mitigation of other threats. Organizations with high dependency on Wireshark tools for network security operations, such as telecom providers, financial institutions, and critical infrastructure operators, may experience operational interruptions. The low severity and requirement for local access and user interaction reduce the likelihood of widespread exploitation, but targeted attacks or accidental crashes remain concerns.

To mitigate this vulnerability, European organizations should: 1) Avoid using affected versions (3.6.0, 4.0.0, 4.2.0) of editcap until a patch is released; 2) Restrict access to editcap binaries to trusted users only, minimizing exposure to untrusted capture files; 3) Implement strict validation and scanning of capture files before processing to detect malformed or suspicious content; 4) Use sandboxing or containerization when running editcap to contain potential crashes and prevent broader system impact; 5) Monitor logs and system behavior for signs of crashes or abnormal editcap activity; 6) Stay updated with Wireshark Foundation advisories for patches or further guidance; 7) Educate users on the risks of opening untrusted capture files and enforce policies to avoid processing files from unknown sources.
