Cisco: Security Vulnerabilities
A vulnerability in Cisco IOS Software for Cisco Catalyst 2960X, 2960XR, 2960CX, and 3560CX Series Switches could allow an authenticated, local attacker with privilege level 15 or an unauthenticated attacker with physical access to the device to execute persistent code at boot time and break the chain of trust.
This vulnerability is due to missing signature verification for specific files that may be loaded during the device boot process. An attacker could exploit this vulnerability by placing a crafted file into a specific location on an affected device. A successful exploit could allow the attacker to execute arbitrary code at boot time.
Because this allows the attacker to bypass a major security feature of the device, Cisco has raised the Security Impact Rating (SIR) of this advisory from Medium to High.

A vulnerability in the CLI of Cisco Catalyst SD-WAN Manager, formerly Cisco SD-WAN vManage, could allow an authenticated, local attacker to gain privileges of the root user on the underlying operating system.
This vulnerability is due to insufficient input validation. An authenticated attacker with read-only privileges on the SD-WAN Manager system could exploit this vulnerability by sending a crafted request to the CLI of the SD-WAN Manager. A successful exploit could allow the attacker to gain root privileges on the underlying operating system.

A vulnerability in the access control list (ACL) programming of Cisco IOS Software that is running on Cisco Catalyst 1000 Switches and Cisco Catalyst 2960L Switches could allow an unauthenticated, remote attacker to bypass a configured ACL.
This vulnerability is due to the use of both an IPv4 ACL and a dynamic ACL of IP Source Guard on the same interface, which is an unsupported configuration. An attacker could exploit this vulnerability by attempting to send traffic through an affected device. A successful exploit could allow the attacker to bypass an ACL on the affected device.
Note: Cisco documentation has been updated to reflect that this is an unsupported configuration. However, Cisco is publishing this advisory because the device will not prevent an administrator from configuring both features on the same interface. There are no plans to implement the ability to configure both features on the same interface on Cisco Catalyst 1000 or Catalyst 2960L Switches.

A vulnerability in the Wireless Network Control daemon (wncd) of Cisco IOS XE Software for Wireless LAN Controllers (WLCs) could allow an unauthenticated, adjacent wireless attacker to cause a denial of service (DoS) condition.
This vulnerability is due to improper memory management. An attacker could exploit this vulnerability by sending a series of IPv6 network requests from an associated wireless IPv6 client to an affected device. To associate a client to a device, an attacker may first need to authenticate to the network, or associate freely in the case of a configured open network. A successful exploit could allow the attacker to cause the wncd process to consume available memory and eventually cause the device to stop responding, resulting in a DoS condition.

A vulnerability in the web-based management interface of Cisco Catalyst SD-WAN Manager, formerly Cisco SD-WAN vManage, could allow an authenticated, remote attacker to conduct a stored cross-site scripting attack (XSS) on an affected system.
This vulnerability is due to improper sanitization of user input to the web-based management interface. An attacker could exploit this vulnerability by submitting a malicious script through the interface. A successful exploit could allow the attacker to conduct a stored XSS attack on the affected system.

CVE-2025-32433
Erlang/OTP is a set of libraries for the Erlang programming language. Prior to versions OTP-27.3.3, OTP-26.2.5.11, and OTP-25.3.2.20, a SSH server may allow an attacker to perform unauthenticated remote code execution (RCE). By exploiting a flaw in SSH protocol message handling, a malicious actor could gain unauthorized access to affected systems and execute arbitrary commands without valid credentials. This issue is patched in versions OTP-27.3.3, OTP-26.2.5.11, and OTP-25.3.2.20. A temporary workaround involves disabling the SSH server or to prevent access via firewall rules.

A vulnerability in the custom URL parser of Cisco Webex App could allow an unauthenticated, remote attacker to persuade a user to download arbitrary files, which could allow the attacker to execute arbitrary commands on the host of the targeted user.
This vulnerability is due to insufficient input validation when Cisco Webex App processes a meeting invite link. An attacker could exploit this vulnerability by persuading a user to click a crafted meeting invite link and download arbitrary files. A successful exploit could allow the attacker to execute arbitrary commands with the privileges of the targeted user.

A vulnerability in Cisco Nexus Dashboard could allow an unauthenticated, remote attacker to enumerate LDAP user accounts.
This vulnerability is due to the improper handling of LDAP authentication requests. An attacker could exploit this vulnerability by sending authentication requests to an affected system. A successful exploit could allow an attacker to determine which usernames are valid LDAP user accounts.

A vulnerability in the web-based management interface of Cisco Secure Network Analytics could allow an authenticated, remote attacker with valid administrative credentials to execute arbitrary commands as root on the underlying operating system.
This vulnerability is due to insufficient integrity checks within device backup files. An attacker with valid administrative credentials could exploit this vulnerability by crafting a malicious backup file and restoring it to an affected device. A successful exploit could allow the attacker to obtain shell access on the underlying operating system with the privileges of root.

A vulnerability in chat messaging features of Cisco Enterprise Chat and Email (ECE) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition.
This vulnerability is due to improper validation of user-supplied input to chat entry points. An attacker could exploit this vulnerability by sending malicious requests to a messaging chat entry point in the affected application. A successful exploit could allow the attacker to cause the application to stop responding, resulting in a DoS condition. The application may not recover on its own and may need an administrator to manually restart services to recover.
