Vulnerability Details
The official description of CVE-2025-25066 states that this vulnerability allows for a potential stack-based buffer overflow in the function ndpi_address_cache_restore in lib/ndpi_cache.c. It has been classified under CWE-121, which corresponds to stack-based buffer overflow vulnerabilities.
The CVSS score associated with this vulnerability is 8.1, indicating a high severity level. The attack vector is local, requiring access to the system, while the attack complexity is rated as high, suggesting that exploitation requires a sophisticated approach. Privileges required for exploitation are none, and user interaction is not necessary.
The impacts on confidentiality, integrity, and availability are all rated as high, indicating a severe risk to organizations. The vulnerability was published on February 3, 2025.
Technical Analysis
The root cause of this vulnerability lies in a flaw in the memory handling within the ndpi_address_cache_restore function. Specifically, inadequate boundary checks are implemented, allowing for a stack-based buffer overflow. This type of vulnerability can lead to arbitrary code execution if exploited.
The attack vector is classified as local, meaning that an attacker must have local access to the system to exploit this vulnerability. The attack complexity is rated as high, indicating that exploitation requires specific conditions to be met, and the attacker must possess a certain level of skill.
No privileges are required to exploit this vulnerability, and user interaction is not needed. If exploited, the confidentiality, integrity, and availability of the system could be significantly compromised.
Risk & Impact Analysis
Real-world deployment of the ntop ndpi product with this vulnerability poses a significant risk to organizations. Attackers may leverage this vulnerability to perform unauthorized actions, leading to data theft, corruption, or system outages.
The blast radius for this vulnerability could extend to any system running the vulnerable version of ndpi. As the CVSS score indicates a high severity, organizations should assess their risk based on the potential for exploitation and the value of the data at risk.
Given the current lack of known exploitation in the wild, organizations should still treat this vulnerability with urgency and prioritize remediation based on the CVSS score.
