Glexia's Take · Automated analysis
CWE-782: Exposed IOCTL with Insufficient Access Control
Exposed IOCTL with Insufficient Access Control represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
Executive Impact
- Integrity,Availability,Confidentiality: Varies by Context: Attackers can invoke any functionality that the IOCTL offers. Depending on the functionality, the consequences may include code execution, denial-of-service, and theft of data.
Developer Pattern
CWE-782 is the kind of defect developers can usually prevent with explicit validation, safer framework defaults, and tests that exercise hostile input or unsafe state transitions.
