A five-year-old GitLab vulnerability has been exploited in recent attacks, and it's a serious wake-up call for cybersecurity. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has issued an urgent warning, ordering government agencies to patch their systems. This vulnerability, known as CVE-2021-39935, is a server-side request forgery (SSRF) flaw that allows unauthorized access to the CI Lint API. GitLab addressed this issue back in December 2021, but the problem persists and is being actively exploited.
The CI Lint API is a critical component, used to simulate pipelines and validate CI/CD configurations. GitLab's statement at the time was clear: 'External users without developer privileges should not have access to this API.' Yet, the vulnerability remains, and CISA has taken action, adding it to their list of known exploited vulnerabilities.
CISA has given federal agencies a three-week deadline to patch their systems, emphasizing the urgency of the situation. While the directive primarily targets federal entities, CISA has also urged private organizations to prioritize securing their devices against these attacks. 'These vulnerabilities are like open doors for malicious actors,' CISA warns. 'Apply patches, follow security guidelines, or discontinue use if necessary.'
The impact of this vulnerability is widespread, with over 49,000 devices with a GitLab fingerprint exposed online, mostly in China. Nearly 27,000 of these devices are using the default port 443, making them even more vulnerable.
GitLab, a popular DevSecOps platform, boasts over 30 million registered users and is trusted by many Fortune 100 companies. This vulnerability highlights the need for constant vigilance and prompt action in the face of evolving cyber threats.
And here's the kicker: CISA also flagged a critical vulnerability in SolarWinds Web Help Desk, ordering government agencies to patch within just three days. It's a reminder that cybersecurity is an ongoing battle, and staying ahead of the curve is crucial.
