Cisco Secure Web Appliance Range Request Bypass Vulnerability

Cisco Web Security Appliance Stored Cross-Site Scripting Vulnerability

Cisco Secure Email and Web Manager, Secure Email Gateway, and Secure Web Appliance Stored Cross-Site Scripting Vulnerabilities

A vulnerability in the Advanced Malware Protection (AMP) file filtering feature of Cisco AsyncOS Software for Cisco Web Security Appliance (WSA) could allow an unauthenticated, remote attacker to bypass a configured AMP file filtering rule. The file types affected are zipped or archived file types. The vulnerability is due to incorrect and different file hash values when AMP scans the file. An attacker could exploit this vulnerability by sending a crafted email file attachment through the targeted device. An exploit could allow the attacker to bypass a configured AMP file filter. Cisco Bug IDs: CSCvf52943.

Cisco Email Security Appliance Information Disclosure Vulnerability

A vulnerability in the scanning engines of Cisco AsyncOS Software for Cisco Secure Web Appliance, formerly known as Cisco Web Security Appliance (WSA), could allow an unauthenticated, remote attacker to bypass a configured rule, thereby allowing traffic onto a network that should have been blocked. This vulnerability exists because malformed, encoded traffic is not properly detected. An attacker could exploit this vulnerability by connecting through an affected device to a malicious server and receiving malformed HTTP responses. A successful exploit could allow the attacker to bypass an explicit block rule and receive traffic that should have been rejected by the device.

A vulnerability in the URL filtering mechanism of Cisco AsyncOS Software for Cisco Email Security Appliance (ESA) could allow an unauthenticated, remote attacker to bypass the URL reputation filters on an affected device. This vulnerability is due to improper processing of URLs. An attacker could exploit this vulnerability by crafting a URL in a particular way. A successful exploit could allow the attacker to bypass the URL reputation filters that are configured for an affected device, which could allow malicious URLs to pass through the device.

Cisco Content Security Management Appliance Information Disclosure Vulnerability

The ZIP inspection engine in Cisco AsyncOS 8.5 and earlier on the Cisco Email Security Appliance (ESA) does not properly analyze ZIP archives, which allows remote attackers to bypass malware filtering via a crafted archive, aka Bug ID CSCup07934.

Cisco Secure Email and Web Manager and Secure Email Gateway Cross-Site Scripting Vulnerability

A vulnerability in the web-based management interface of Cisco AsyncOS Software for Cisco Secure Email and Web Manager and Secure Web Appliance could allow an authenticated, remote attacker to conduct an 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.

Cisco AsyncOS on Email Security Appliance (ESA) and Content Security Management Appliance (SMA) devices, when Active Directory is enabled, does not properly handle group names, which allows remote attackers to gain role privileges by leveraging group-name similarity, aka Bug ID CSCum86085.

The uuencode inspection engine in Cisco AsyncOS on Cisco Email Security Appliance (ESA) devices 8.5 and earlier allows remote attackers to bypass intended content restrictions via a crafted e-mail attachment with uuencode encoding, aka Bug ID CSCzv54343.

Multiple cross-site scripting (XSS) vulnerabilities in the IronPort Spam Quarantine (ISQ) page in Cisco AsyncOS, as used on the Cisco Email Security Appliance (ESA) and Content Security Management Appliance (SMA), allow remote attackers to inject arbitrary web script or HTML via unspecified parameters, aka Bug IDs CSCus22925 and CSCup08113.
