Feb 5, 2025A vulnerability in Simple Network Management Protocol (SNMP) polling for Cisco Secure Email and Web Manager, Cisco Secure Email Gateway, and Cisco Secure Web ApCVE-2025-20207 · Network & remote access · Cisco · reported by psirt@cisco.comMedium 4.3
A vulnerability in Simple Network Management Protocol (SNMP) polling for Cisco Secure Email and Web Manager, Cisco Secure Email Gateway, and Cisco Secure Web Appliance could allow an authenticated, remote attacker to obtain confidential information about the underlying operating system. This vulnerability exists because the appliances do not protect confidential information at rest in response to SNMP poll requests. An attacker could exploit this vulnerability by sending a crafted SNMP poll request to the affected appliance. A successful exploit could allow the attacker to discover confidential information that should be restricted. To exploit this vulnerability, an attacker must have the configured SNMP credentials.

A vulnerability in the web-based management interface of Cisco AsyncOS Software for Cisco Secure Email and Web Manager and Secure Email Gateway could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the interface. This vulnerability is due to insufficient validation of user input. An attacker could exploit this vulnerability by persuading a user of an affected interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information. To exploit this vulnerability, the attacker must have valid credentials for a user account with at least the role of Operator.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
