Critical Command Injection Flaw Undermines DSAI-Cline Security
CVE Notify has detailed a critical OS command injection vulnerability impacting DSAI-Clineβs command auto-approval module. This flaw effectively bypasses the moduleβs whitelist security, a serious issue given its reliance on string parsing for command validation. While DSAI-Cline is designed to intercept dangerous operators like semicolons, logical operators, pipes, and command substitution, it overlooks a fundamental weakness: raw newline characters.
Exploitation involves crafting an input where a whitelisted command is followed by a newline and then malicious code. CVE Notify explains that DSAI- Cline misinterprets this as a safe operation. However, the underlying PowerShell interpreter sees the newline as a command separator, executing both the legitimate and the attacker-controlled commands sequentially. The result is Remote Code Execution (RCE) without any user interaction, a nightmare scenario for any system administrator.
What This Means For You
- Security teams should audit systems using DSAI-Cline or similar command parsing modules to ensure they implement robust input validation beyond simple operator stripping, specifically addressing newline characters and other less obvious separators that can be abused by attackers to chain commands.
