Nuclei Vulnerability: How Hackers Bypassed Signature Checks With a Simple Line Break!
Nuclei vulnerability, CVE-2024-43405, allowed attackers to bypass signature verification and sneak malicious code into templates. The flaw, caused by Go regex and YAML parser handling discrepancies, was fixed in Nuclei v3.3.2. Users are advised to update to the latest version and use Nuclei in isolated environments.
Hot Take:
Looks like Nuclei’s open-source vulnerability scanner itself had a vulnerability! Talk about irony. It’s like finding out your home security camera was filming a soap opera instead of intruders. But fear not, the script has been rewritten, and the show must go on—without the hackers!
