Nuclei Vulnerability: When Regex Goes Rogue – Update Now!
Nuclei, the popular open-source vulnerability scanner, had a flaw allowing attackers to bypass signature verification, tracked as CVE-2024-43405. This Go regex issue let malicious code slip past security checks. Fortunately, the vulnerability is now fixed, so update to Nuclei v3.3.2 pronto or risk becoming a hacker’s favorite playground!
Hot Take:
Who knew that a pesky, misplaced line break could turn your vulnerability scanner into a vulnerability inviter? If only Nuclei had hired a proofreader. But hey, at least they’ve patched it up before it became a sequel to “The Ring”—one line break to rule them all!
Key Points:
- Nuclei had a vulnerability (CVE-2024-43405) that allowed template signature verification bypass.
