AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
Securly Chrome Extension 3.0.7 is vulnerable to DoS via catastrophic backtracking due to unvalidated JavaScript regular expressions compiled from HTTP-downloaded configuration.
Vulnerability
Version 3.0.7 of the Securly Chrome Extension downloads config.json over HTTP. It then compiles server-provided patterns into JavaScript regular expressions using new RegExp() without performing complexity validation. This allows for the injection of patterns that can cause catastrophic backtracking.
Exploitation
An attacker in an on-path network position can intercept the config.json download and inject malicious patterns. When the extension compiles these patterns into regular expressions, the catastrophic backtracking will be triggered, leading to a denial of service.
Impact
Successful exploitation results in a denial of service for all browsing activities on the affected user's machine. This prevents the user from accessing any web content.
Mitigation
Not yet disclosed in the available references.
