Trend Micro recently patched two high-severity vulnerabilities affecting some of its hybrid cloud security products. Details and proof-of-concept (PoC) exploits have been released by the researchers who found the flaws.
The vulnerabilities are tracked as CVE-2022-23119 and CVE-2022-23120, and they impact Deep Security and Cloud One workload security solutions, specifically the Linux agent component.
The vulnerabilities were discovered by researchers at Swiss-German cybersecurity firm modzero, which released an advisory and PoC exploits on January 19, the same day Trend Micro announced the patches.
It’s worth noting, however, that the flaws were reported to Trend Micro in September and patches were released in October, November and December.
Modzero discovered that the Deep Security Agent for Linux is affected by a directory traversal vulnerability that could allow an attacker to read arbitrary files, and a code injection issue that could be exploited to escalate privileges and execute code as root.
However, the attacker needs to have access to the targeted system and exploitation is only possible if the agent has not been activated or configured.
Modzero’s advisory also mentions that a hardcoded default X.509 certificate and a corresponding private key are shipped with the agent software. The certificate is used for communications with the server before the agent is activated.
“As this certificate ships with a private key it is possible for an attacker to create and sign their own server certificate, imitate a server and to send commands to the client software,” Modzero explained.
Last week, Trend Micro informed customers about an information disclosure flaw affecting its Worry-Free Business Security small business product. However, that bug was assigned a “low severity” rating.
Vulnerabilities in Trend Micro products have been known to be exploited by malicious actors, particularly flaws in the cybersecurity firm’s Apex One products.
