QNAP Working on Patches for OpenSSL Flaws Affecting its NAS Devices

September 1, 2021

Community-attached storage (NAS) equipment maker QNAP mentioned it is currently investigating two just lately patched safety flaws in OpenSSL to find out their potential affect, including it’ll launch safety updates ought to its merchandise change into susceptible.

Tracked as CVE-2021-3711 (CVSS rating: 7.5) and CVE-2021-3712 (CVSS rating: 4.4), the weaknesses concern a high-severity buffer overflow in SM2 decryption perform and a buffer overrun difficulty when processing ASN.1 strings that might be abused by adversaries to run arbitrary code, trigger a denial-of-service situation, or end in disclosure of personal reminiscence contents, comparable to personal keys, or delicate plaintext —

“A malicious attacker who is ready current SM2 content material for decryption to an utility may trigger attacker chosen information to overflow the buffer by as much as a most of 62 bytes altering the contents of different information held after the buffer, presumably altering utility behaviour or inflicting the applying to crash,” based on the advisory for CVE-2021-3711.

Stack Overflow Teams

OpenSSL, a broadly used open-source cryptographic library that gives encrypted connections utilizing Safe Sockets Layer (SSL) or Transport Layer Safety (TLS), addressed the issues in variations OpenSSL 1.1.1l and 1.0.2za that had been shipped on August 24.

In the mean time, NetApp on Tuesday confirmed that the issues have an effect on the next merchandise, whereas it continues to evaluate the remainder of its lineup —

  • Clustered Knowledge ONTAP
  • Clustered Knowledge ONTAP Antivirus Connector
  • E-Sequence SANtricity OS Controller Software program 11.x
  • NetApp Manageability SDK
  • NetApp SANtricity SMI-S Supplier
  • NetApp SolidFire & HCI Administration Node
  • NetApp Storage Encryption

The event follows days after NAS maker Synology additionally disclosed that it is opened an investigation into various fashions, comprising DSM 7.0, DSM 6.2, DSM UC, SkyNAS, VS960HD, SRM 1.2, VPN Plus Server, and VPN Server, to test if they’re affected by the identical two flaws.

Prevent Ransomware Attacks

“A number of vulnerabilities enable distant attackers to conduct denial-of-service assault[s] or presumably execute arbitrary code through a inclined model of Synology DiskStation Supervisor (DSM), Synology Router Supervisor (SRM), VPN Plus Server or VPN Server,” the Taiwanese firm said in an advisory.

Different corporations whose merchandise depend on OpenSSL have additionally launched safety bulletins, together with —
