Openssl vulnerability4/12/2023 The best possible mitigation is suggested to be upgrading to the latest version.ĬVSSv3 info edit VulDB Meta Base Score: 3.7 Applying the patch 919925673d6c9cfed3c1085497f5dfbbed5fc431 is able to eliminate this problem. Upgrading to version 1.1.1q or 3.0.5 eliminates this vulnerability. MITRE ATT&CK project uses the attack technique T1600 for this issue. The price for an exploit might be around USD $0-$5k at the moment ( estimation calculated on ). Neither technical details nor an exploit are publicly available. This vulnerability is known as CVE-2022-2097 since. The weakness was released as 20220705.txt. Since OpenSSL does not support OCB based cipher suites for TLS and DTLS, they are both unaffected. In the special case of "in place" encryption, sixteen bytes of the plaintext would be revealed. This could reveal sixteen bytes of data that was preexisting in the memory that wasn't written. The summary by CVE is:ĪES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimised implementation will not encrypt the entirety of the data under some circumstances. The software does not encrypt sensitive or critical information before storage or transmission. The CWE definition for the vulnerability is CWE-311. The manipulation with an unknown input leads to a weak encryption vulnerability. Affected by this vulnerability is an unknown code of the component AES OCB Mode. A high score indicates an elevated risk to be targeted for this vulnerability.Ī vulnerability classified as problematic was found in OpenSSL up to 1.1.1p/3.0.4 on 32-bit ( Network Encryption Software). The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. Details about both vulnerabilities can be found in the linked security advisories.Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. This allows the application to be crashed in a targeted manner by manipulated data packets as part of a denial of service attack. Here, the data structure for implementing ASN.1 strings leads to an attacker being able to create a buffer overflow. Vulnerability CVE-2021-3712, on the other hand, is rated as moderate. The OpenSLL developers do not say anything about whether code execution is also possible – but Synology does not want to rule this out. An attacker could provoke a buffer overflow via appropriately manipulated content, which leads to a crash of the application. A flaw in the implementation of the SM2 decryption code could lead to a buffer overflow in the affected routines. Vulnerability CVE-2021-3711 has a CVE score of 8.1 and is rated Important. The following software products are affected and no security updates are available as of August 26, 2021: Product The two vulnerabilities CVE-2021-3711 and CVE-2021-3712 in OpenSSL also affect the security of Synology DiskStation Manager (DSM), Synology Router Manager (SRM), VPN Plus Server or VPN Server. Synology has published the security alert Synology-SA-21:24 OpenSSL with details. German blog reader Ralf just pointed this out in this comment (thanks for that). OpenSSL has released a security update version 1.1.1k) to fix two vulnerabilities CVE-2021-3711 and CVE-2021-3712.
