Cisco Products Multiple Vulnerabilities

Multiple vulnerabilities were identified in Cisco products. A remote attacker could exploit some of these vulnerabilities to trigger denial of service condition, elevation of privilege, spoofing, remote code execution, sensitive information disclosure, cross-site scripting, data manipulation and security restriction bypass on the targeted system.

Note:

CVE-2026-20131 is being exploited in the wild. This vulnerability is due to insecure deserialization of a user-supplied Java byte stream. An attacker could exploit this vulnerability by sending a crafted serialized Java object to the web-based management interface of an affected device. A successful exploit could allow the attacker to execute arbitrary code on the device and elevate privileges to root. If the FMC management interface does not have public internet access, the attack surface that is associated with this vulnerability is reduced. Hence, the risk level is rated from Medium Risk to High Risk.
