Researchers have disclosed aspects of critical security vulnerabilities in TerraMaster network-connected storage (TNAS) units that could be chained to achieve unauthenticated distant code execution with the best privileges.
The issues reside in TOS, an abbreviation for TerraMaster Working Technique, and “can grant unauthenticated attackers access to the victim’s box simply just by being aware of the IP deal with, Ethiopian cyber security study organization Octagon Networks’ Paulos Yibelo explained in a assertion shared with The Hacker News.
TOS is the working method designed for TNAS appliances, enabling end users to manage storage, install apps, and backup knowledge. Next responsible disclosure, the flaws were patched in TOS version 4.2.30 introduced final week on March 1, 2022.
A person of the issues, tracked as CVE-2022-24990, fears a case of info leak in a part termed “webNasIPS,” ensuing in the publicity of TOS firmware version, the default gateway interface’s IP and MAC handle, and a hash of the administrator password.
The second shortcoming, on the other hand, relates to a command injection flaw in a PHP module named “createRaid” (CVE-2022-24989), resulting in a situation in which the two issues can be stringed together to submit a specifically-crafted command to realize distant code execution.
“All in all, this was a incredibly fascinating project,” Yibelo explained. “We have utilised many parts of an details leak, along with one more data leak of the machine’s time, and chained it with an authenticated OS command injection to obtain unauthenticated remote code execution as root.
The disclosure comes as TerraMaster NAS equipment have also been subjected to Deadbolt ransomware attacks, becoming a member of the likes of QNAP and ASUSTOR, with the firm noting that it dealt with the vulnerabilities that have been probably exploited by the danger actors to deploy the ransomware in TOS edition 4.2.30.
It really is not instantly distinct if the identical established of vulnerabilities uncovered by Octagon Networks ended up weaponized for Deadbolt bacterial infections. We have attained out to TerraMaster for more comment, and we will update the story if we hear back.
“Fixed a security vulnerability similar to the Deadbolt ransomware attack,” the enterprise pointed out, recommending buyers to “re-put in the most current variation of the TOS system (4.2.30 or afterwards) to avert unencrypted files from continuing to be encrypted.
