Synology: Multiple products impacted by OpenSSL RCE vulnerability

Taiwan-based NAS maker Synology has revealed that lately disclosed distant code execution (RCE) and denial-of-service (DoS) OpenSSL vulnerabilities influence a few of its merchandise.

“A number of vulnerabilities enable distant attackers to conduct denial-of-service assault or execute arbitrary code by way of a prone model of Synology DiskStation Supervisor (DSM), Synology Router Supervisor (SRM), VPN Plus Server or VPN Server,” the corporate explains in a security advisory published earlier today.

The entire checklist of gadgets affected by the safety flaws tracked as CVE-2021-3711 and CVE-2021-3712 consists of DSM 7.0, DSM 6.2, DSM UC, SkyNAS, VS960HD, SRM 1.2, VPN Plus Server, and VPN Server.

Patches coming throughout the subsequent 90 days

The primary bug is attributable to a heap-based buffer overflow within the SM2 cryptographic algorithm which usually results in crashes however can be abused by attackers for arbitrary code execution.

The second flaw is a read buffer overrun whereas processing ASN.1 strings that may be exploited to crash susceptible apps in DoS assaults or acquire entry to personal reminiscence contents akin to personal keys or different delicate information.

Though the OpenSSL improvement group has revealed OpenSSL 1.1.1l to handle the 2 flaws on August 24, Synology says that releases for impacted merchandise are both “ongoing” or “pending.”

Whereas Synology doesn’t present an estimated timeline for these incoming updates, the corporate instructed BleepingComputer earlier this month that it usually patches affected software program inside 90 days after publishing advisories.

Product Severity Fastened Launch Availability
DSM 7.0 Necessary Ongoing
DSM 6.2 Average Ongoing
DSM UC Average Ongoing
SkyNAS Average Pending
VS960HD Average Pending
SRM 1.2 Average Ongoing
VPN Plus Server Necessary Ongoing
VPN Server Average Ongoing

DiskStation Supervisor vulnerabilities additionally below investigation

The NAS maker can be engaged on safety updates for a number of DiskStation Supervisor (DSM) vulnerabilities with no assigned CVE IDs and impacting DSM 7.0, DSM 6.2, DSM UC, SkyNAS, and VS960HD.

“A number of vulnerabilities enable distant authenticated customers to execute arbitrary instructions, or distant attackers to jot down arbitrary recordsdata by way of a prone model of DiskStation Supervisor (DSM),” Synology stated when it publicly disclosed these security flaws on August 17.

“Our groups are nonetheless actively investigating this potential vulnerability and CVEs will probably be assigned when extra info could be disclosed,” the corporate instructed BleepingComputer final week when requested to share CVE ID information on these DSM bugs.

Synology additionally added that attackers have not but exploited the vulnerabilities disclosed in final week’s advisory within the wild.

Earlier this month, the corporate warned prospects that the StealthWorker botnet is targeting their network-attached storage (NAS) devices in brute-force assaults that result in ransomware infections.
