Summary

CVE-2025-1492 is a high-severity Uncontrolled Recursion (CWE-674) vulnerability in Wireshark Wireshark. Its CVSS base score is 7.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Endpoint Denial of Service (T1499); ranked at the 22th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and SC-5 (Denial-of-service Protection) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-1492 affects the Bundle Protocol and CBOR dissectors in Wireshark versions 4.4.0 through 4.4.3 and 4.2.0 through 4.2.10. The vulnerability causes crashes in these dissectors, enabling denial of service via packet injection or a crafted capture file. It is associated with CWE-674 and has a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).

Exploitation requires local access with low attack complexity and no privileges, but user interaction is necessary, such as convincing a user to open a malicious capture file or perform a live capture with injected packets. A successful attack results in Wireshark crashes, leading to denial of service with high impacts on confidentiality, integrity, and availability as scored by CVSS.

Wireshark's security advisory (WNPA-SEC-2025-01) and the related issue tracker provide details on mitigation: https://www.wireshark.org/security/wnpa-sec-2025-01.html and https://gitlab.com/wireshark/wireshark/-/issues/20373. The vulnerability was published on 2025-02-20.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Input validation can reject or constrain data that would otherwise drive unbounded recursive calls.

DoS protection mechanisms limit the resource-exhaustion impact of uncontrolled recursion without eliminating the flaw.

System monitoring can observe anomalous resource consumption that signals runaway recursion after it begins.

finds

Security testing in development can detect excessive recursion via static analysis or fuzzing.

prevents

Secure development life cycle requires controls that prevent uncontrolled recursion through design and code review.

prevents

Application security requirements can mandate recursion limits or stack-depth checks.

prevents

Secure system architecture principles include resource-management and input-validation rules that limit recursion.

prevents

Secure coding standards directly prohibit or constrain recursive constructs that could exhaust stack or memory.

finds

Capacity management includes monitoring and limits that mitigate resource exhaustion from runaway recursion.
