DescriptionNVD

Buffer overflow in OPC UA applications allows remote attackers to trigger a stack overflow with carefully structured requests.

AnalysisAI

Buffer overflow in OPC UA applications allows remote attackers to trigger a stack overflow with carefully structured requests. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.

Technical ContextAI

This vulnerability is classified as Out-of-bounds Write (CWE-787), which allows attackers to write data beyond allocated buffer boundaries leading to code execution or crashes. Buffer overflow in OPC UA applications allows remote attackers to trigger a stack overflow with carefully structured requests. Affected products include: Opcfoundation Unified Architecture-.Net-Legacy, Opcfoundation Unified Architecture-Java, Opcfoundation Unified Architecture .Net-Standard, Opcfoundation Unified Architecture Ansic, Debian Debian Linux.

RemediationAI

No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate write boundaries, use memory-safe languages, enable compiler protections (ASLR, stack canaries).
