Cisco has flagged two extra Catalyst SD-WAN Supervisor safety flaws as actively exploited within the wild, urging directors to improve weak units.
Catalyst SD-WAN Supervisor (previously vManage) is community administration software program that permits admins to observe and handle as much as 6,000 Catalyst SD-WAN units from a single centralized dashboard.
“In March 2026, the Cisco PSIRT grew to become conscious of lively exploitation of the vulnerabilities which can be described in CVE-2026-20128 and CVE-2026-20122 solely,” the corporate warned in an replace to a February 25 advisory.
“The vulnerabilities which can be described within the different CVEs on this advisory aren’t identified to have been compromised. Cisco strongly recommends that prospects improve to a set software program launch to remediate these vulnerabilities.”
The high-severity arbitrary file overwrite vulnerability (CVE-2026-20122) can solely be exploited by distant attackers with legitimate read-only credentials with API entry, whereas the medium-severity data disclosure flaw (CVE-2026-20128) requires native attackers to have legitimate vmanage credentials on the focused methods.
Cisco added that these vulnerabilities have an effect on Catalyst SD-WAN Supervisor software program, no matter machine configuration.
SD-WAN zero-days exploited since 2023
Final week, the corporate additionally disclosed {that a} vital authentication bypass vulnerability (CVE-2026-20127) has been exploited in zero-day assaults since a minimum of 2023, enabling extremely refined menace actors to compromise controllers and add malicious rogue friends to focused networks.
The rogue friends enable the attackers to insert legitimate-looking malicious units, enabling them to maneuver deeper into compromised networks.
After joint advisories by U.S. and U.Okay. authorities warning of the exploitation exercise, CISA issued Emergency Directive 26-03 requiring federal businesses to stock Cisco SD-WAN methods, gather forensic artifacts, guarantee exterior log storage, apply updates, and examine potential compromises tied to assaults focusing on CVE-2026-20127 and an older flaw tracked as CVE-2022-20775.
Extra not too long ago, on Wednesday, Cisco launched safety updates to patch two maximum-severity vulnerabilities in its Safe Firewall Administration Middle (FMC) software program.
These safety flaws, an authentication bypass flaw (tracked as CVE-2026-20079) and a distant code execution (RCE) vulnerability (CVE-2026-20131), will be exploited remotely by unauthenticated attackers to achieve root entry to the underlying working system and execute arbitrary Java code as root on unpatched units, respectively.
