"Cisco Patches High-Severity Vulnerabilities in ACI Components"

Cisco recently informed customers about the availability of patches for two high-severity vulnerabilities affecting components of its Application Centric Infrastructure (ACI) software-defined networking solution.  Cisco noted that one of these flaws, CVE-2023-20011, impacts the management interface of the Cisco Application Policy Infrastructure Controller (APIC) and Cloud Network Controller.  APIC is the unified point of automation and management for ACI.  Cisco stated that the vulnerability can be exploited by a remote, unauthenticated attacker to conduct cross-site request forgery (CSRF) attacks by tricking a user into clicking on a malicious link.  The attacker could then conduct activities on the targeted system with the privileges of the compromised user.  The researchers noted that the second high-severity issue, CVE-2023-20089, affects Cisco Nexus 9000 series Fabric switches in ACI mode, and it can be exploited for denial-of-service (DoS) attacks by an unauthenticated, adjacent attacker.  The vendor noted that certain conditions need to be met for exploitation.  Cisco stated that both security holes were discovered internally, and there is no evidence of malicious exploitation.  In addition, Cisco recently announced that it had patched medium-severity flaws in several products, including a UCS Manager and FXOS software issue that exposes backup files, a command injection bug in NX-OS, a command injection in Firepower appliances, and an authentication bypass vulnerability in Nexus extenders (requires physical access).  Cisco has also released an informational advisory for a privilege escalation issue related to products running NX-OS software and configured for SSH authentication with an X.509v3 certificate.
