QNAP works on patches for OpenSSL bugs impacting its NAS devices

Community-attached storage (NAS) maker QNAP is investigating and dealing on safety updates to deal with distant code execution (RCE) and denial-of-service (DoS) vulnerabilities patched by OpenSSL final week.

The safety flaws tracked as CVE-2021-3711 and CVE-2021-3712, impression QNAP NAS gadget operating QTS, QuTS hero, QuTScloud, and HBS 3 Hybrid Backup Sync (a backup and catastrophe restoration app), in keeping with advisories [1, 2] printed earlier at this time.

The heap-based buffer overflow within the SM2 cryptographic algorithm behind CVE-2021-3711 would seemingly result in crashes however will also be abused by attackers for arbitrary code execution.

The CVE-2021-3712 vulnerability is brought on by a read buffer overrun weak spot whereas processing ASN.1 strings. Risk actors can exploit it to crash susceptible apps or achieve entry to non-public reminiscence contents equivalent to non-public keys or related delicate data.

As QNAP explains, if efficiently exploited, the vulnerabilities permit distant attackers to achieve entry to reminiscence knowledge with out authorization, set off denial-of-service (DoS) states, or run arbitrary code with the permissions of the person operating the HBS 3 app.

Whereas the OpenSSL improvement crew printed OpenSSL 1.1.1l to deal with the failings every week in the past, on August 24, QNAP didn’t present an estimated time of arrival for incoming safety updates.

Nonetheless, the corporate did say that it is “totally investigating the case” and “will launch safety updates and supply additional info as quickly as potential.”

Synology clients additionally ready for safety updates

Final week, Taiwan-based NAS maker Synology also said a number of fashions in its NAS line (together with DSM 7.0, DSM 6.2, DSM UC, SkyNAS, VS960HD, SRM 1.2, VPN Plus Server, and VPN Server) are affected by the identical two safety flaws.

“A number of vulnerabilities permit distant attackers to conduct denial-of-service assault or execute arbitrary code by way of a inclined model of Synology DiskStation Supervisor (DSM), Synology Router Supervisor (SRM), VPN Plus Server or VPN Server,” the corporate defined.

Simply as QNAP, Synology hasn’t but issued safety updates to deal with these flaws, tagging them as “pending” and “ongoing.”

Earlier this month, Palo Alto Networks’ Unit 42 revealed {that a} newly found eCh0raix ransomware variant had added support for encrypting both QNAP and Synology NAS devices.

One month earlier, QNAP fixed a critical HBS 3 security vulnerability that enabled attackers to escalate privileges, learn delicate data with out authorization, or execute instructions remotely.
