Summary

CVE-2025-25066 is a high-severity Stack-based Buffer Overflow (CWE-121) vulnerability in Ntop Ndpi. Its CVSS base score is 8.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 7th 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 SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

CVE-2025-25066, published on 2025-02-03, is a potential stack-based buffer overflow vulnerability (CWE-121) in the ndpi_address_cache_restore function located in lib/ndpi_cache.c of nDPI through version 4.12. This flaw carries a CVSS v3.1 base score of 8.1 (AV:L/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H), indicating high severity due to its potential for significant impact across confidentiality, integrity, and availability with a changed scope.

The vulnerability can be exploited by a local attacker requiring no privileges (PR:N), though it demands high attack complexity (AC:H) and no user interaction (UI:N). With local access vector (AV:L), a successful exploit could grant the attacker high-level control, potentially enabling arbitrary code execution, data corruption, or system crashes, while the changed scope (S:C) allows impacts beyond the vulnerable component.

Mitigation is addressed in a patch via the GitHub commit at https://github.com/ntop/nDPI/commit/678697b5eb6c3caa5dd5f8cccfe9eed8d13b94bb. Security practitioners should apply this fix by updating nDPI to a patched version to prevent exploitation.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and analysis can discover stack-buffer overflows before deployment.

Input validation directly stops untrusted data from exceeding stack buffer bounds.

Memory-protection mechanisms limit the ability to execute injected code after a stack overflow.

Secure-engineering principles include bounds-checked coding and safe buffer handling that avoid introducing the flaw.
