Recently, a critical vulnerability known as CVE-2025-25066 has surfaced, impacting the Cisco nDPI (Network Detection and Response Platform) stack. This vulnerability points to a stack-based buffer overflow issue, which can allow malicious actors to inject harmful scripts via the cargo parameter. Storing and executing these scripts on servers can lead to severe consequences for organizations relying on the Cisco nDPI stack, particularly those still using versions up to 4.12. Discovered on January 5, 2025, this vulnerability puts affected systems at high risk of exploitation, thus raising alarms in the cybersecurity community.
What Is CVE-2025-25066?
CVE-2025-25066 is categorized as a critical vulnerability due to its capacity for arbitrary code execution. Attackers can potentially gain control over the affected systems because of a flaw located in the ndpi_address_cache_restore function found within lib/ndpi_cache.c of the nDPI. Such vulnerabilities, especially stack-based buffer overflows, can severely affect the system’s confidentiality, integrity, and availability.
Timeline and Current Status
- Discovery Date: January 5, 2025
- Disclosure Date: February 3, 2025
- CVSS Score: Ranges from 7.0 to 8.1, indicating its severity.
This flaw has not yet been fully analyzed by the National Vulnerability Database (NVD) but has already drawn significant attention due to its potential impact.
How to Mitigate the Risk
To protect against CVE-2025-25066, organizations should:
- Update nDPI: Ensure that you are using a version higher than 4.12 to avoid exposure.
- Monitor for Updates: Keep an eye on the NVD for the latest analysis and guidance on this vulnerability.
- Implement Security Best Practices: Regularly review your network defenses and employ best cybersecurity practices.
Impact of the Vulnerability
This stack-based buffer overflow vulnerability not only jeopardizes confidentiality but also compromises system integrity. Reports indicate that the exploitation requires local access, making it relatively more challenging, but doable for those with malicious intent. Still, organizations should not underestimate the critical nature of this vulnerability.
