AlienVault OTX Vulnerabilities

AlienVault OTX Malware

An improper validation of integrity check value vulnerability exists in 

AVEVA PI Connector for CygNet Versions 1.6.14 and prior that, if exploited, 
could allow a miscreant with elevated privileges to modify PI Connector 
for CygNet local data files (cache and buffers) in a way that causes the
 connector service to become unresponsive.

CVE-2025-4418 is a medium-severity vulnerability identified in AVEVA PI Connector for CygNet, specifically in versions 1.6.14 and prior. The vulnerability is categorized under CWE-354, which relates to improper validation of integrity check values. This flaw allows an attacker with elevated privileges on the affected system to manipulate local data files used by the PI Connector for CygNet, such as cache and buffer files. By modifying these files improperly, the attacker can cause the connector service to become unresponsive, effectively resulting in a denial-of-service (DoS) condition. The vulnerability does not impact confidentiality or integrity of data directly but affects availability by disrupting the normal operation of the connector service. The CVSS 3.1 base score is 4.4, reflecting a medium severity level, with the vector indicating that the attack requires local access (AV:L), low attack complexity (AC:L), high privileges (PR:H), no user interaction (UI:N), and impacts availability only (A:H) without affecting confidentiality or integrity. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability is significant in industrial control system (ICS) environments where AVEVA PI Connector for CygNet is deployed to interface with CygNet SCADA systems, commonly used in critical infrastructure sectors such as energy, utilities, and manufacturing. The improper validation of integrity checks suggests that the software does not adequately verify the authenticity or correctness of its local data files before processing, allowing privileged users to disrupt service by tampering with these files.
