The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added three security flaws to its Known Exploited Vulnerabilities (KEV) catalog, citing evidence of active exploitation.
The list of vulnerabilities is below -
- CVE-2022-35914 (CVSS score: 9.8) - Teclib GLPI Remote Code Execution Vulnerability
- CVE-2022-33891 (CVSS score: 8.8) - Apache Spark Command Injection Vulnerability
- CVE-2022-28810 (CVSS score: 6.8) - Zoho ManageEngine ADSelfService Plus Remote Code Execution Vulnerability
The most critical of the three is CVE-2022-35914, which concerns a remote code execution vulnerability in the third-party library htmlawed present in Teclib GLPI, an open source asset and IT management software package.
The exact specifics surrounding the nature of attacks are unknown, but the Shadowserver Foundation in October 2022 noted that it has seen exploitation attempts against its honeypots.
Since then, a cURL-based one-line proof of concept (PoC) has been made available on GitHub and a "mass" scanner has been advertised for sale, VulnCheck security researcher Jacob Baines said in December 2022.
Furthermore, data gathered by GreyNoise has revealed 40 malicious IP addresses from the U.S., the Netherlands, Hong Kong, Australia, and Bulgaria, attempting to abuse the shortcoming.
The second flaw is an unauthenticated command injection vulnerability in Apache Spark that has been exploited by the Zerobot botnet to co-opt susceptible devices with the goal of carrying out distributed denial-of-service (DDoS) attacks.
Lastly, also added to the KEV catalog is a remote code execution flaw in Zoho ManageEngine ADSelfService Plus that was patched in April 2022.

"Multiple Zoho ManageEngine ADSelfService Plus contains an unspecified vulnerability allowing for remote code execution when performing a password change or reset," CISA said.
Cybersecurity company Rapid7, which discovered the bug, said it detected active exploitation attempts by threat actors to "execute arbitrary OS commands in order to gain persistence on the underlying system and attempt to pivot further into the environment."
The development comes as API security firm Wallarm said it has found ongoing exploit attempts of two VMware NSX Manager flaws (CVE-2021-39144 and CVE-2022-31678) since December 2022 that could be leveraged to execute malicious code and siphon sensitive data.
Update: CISA Adds CVE-2021-39144 to KEV Catalog
CISA on March 10, 2023, added CVE-2021-39144 to its catalog of security flaws exploited in the wild, alongside CVE-2020-5741, a remote code execution bug impacting Plex Media Server that was exploited in the LastPass breach.
Virtualization services provider VMware has also revised its October 2022 advisory to confirm reports of active exploitation of CVE-2021-39144.
