CVE-2025-20153ciscocisco secure email+1
EPSS score0.36%
A vulnerability in the email filtering mechanism of Cisco Secure Email Gateway could allow an unauthenticated, remote attacker to bypass the configured rules and allow emails that should have been denied to flow through an affected device.
This vulnerability is due to improper handling of email that passes through an affected device. An attacker could exploit this vulnerability by sending a crafted email through the affected device. A successful exploit could allow the attacker to bypass email filters on the affected device.CVE-2024-20401ciscocisco secure email+1EPSS score2.26%
A vulnerability in the content scanning and message filtering features of Cisco Secure Email Gateway could allow an unauthenticated, remote attacker to overwrite arbitrary files on the underlying operating system.
This vulnerability is due to improper handling of email attachments when file analysis and content filters are enabled. An attacker could exploit this vulnerability by sending an email that contains a crafted attachment through an affected device. A successful exploit could allow the attacker to replace any file on the underlying file system. The attacker could then perform any of the following actions: add users with root privileges, modify the device configuration, execute arbitrary code, or cause a permanent denial of service (DoS) condition on the affected device.
Note: Manual intervention is required to recover from the DoS condition. Customers are advised to contact the Cisco Technical Assistance Center (TAC) to help recover a device in this condition.CVE-2023-20028ciscocisco web security appliance (wsa)+3EPSS score0.47%
Multiple vulnerabilities in the web-based management interface of Cisco AsyncOS Software for Cisco Secure Email and Web Manager; Cisco Secure Email Gateway, formerly Cisco Email Security Appliance (ESA); and Cisco Secure Web Appliance, formerly Cisco Web Security Appliance (WSA), could allow a remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface. For more information about these vulnerabilities, see the Details section of this advisory.CVE-2023-20119ciscocisco secure email and web manager+3EPSS score0.51%
A vulnerability in the web-based management interface of Cisco AsyncOS Software for Cisco Secure Email and Web Manager, formerly known as Content Security Management Appliance (SMA) could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface.
This vulnerability is due to insufficient user input validation. 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.CVE-2023-20120ciscocisco web security appliance (wsa)+3EPSS score0.47%
