GLPI Exploitation Timeline
As part of our Exploit Intelligence service, VulnCheck tracks vulnerabilities exploited in the wild. Prioritizing known exploited vulnerabilities for remediation is a smart strategy to minimize vulnerability risk. However, that strategy breaks down when some exploited vulnerabilities are overlooked. For CVE published in 2022, VulnCheck is tracking 37 more exploited vulnerabilities than the CISA KEV Catalog. One vulnerability that we’re tracking and KEV isn’t is CVE-2022-35914, a trivial unauthenticated and remote command execution vulnerability affecting GLPI. GLPI is open source software that can serve as a helpdesk, asset manager, administrator, and more. Exposing critical IT management software to the internet is a mistake the security industry sees often. Censys can find approximately 15,000 internet-facing GLPI instances. Shodan doesn’t see half as many instances as Censys, but it is able to create an interesting historical graph of internet-facing GLPI services. Shadowserver tweeted about active exploitation in the middle of October. A couple of months have passed since GLPI and Shadowserver shared their observations regarding active exploitation of CVE-2022-35914. We think it’s useful to know if the vulnerability is still under active exploitation. There are two sources that can help us quickly answer that question. First, Shadowserver maintains a useful honeypot dashboard that lists all the vulnerabilities they’ve seen exploited recently. The other source we can turn to is GreyNoise. Prioritizing the remediation of vulnerabilities exploited in the wild is a solid vulnerability management strategy. But relying on a single source of information with an incomplete dataset could result in disaster.
