CVE-2018-0087
A vulnerability in the FTP server of the Cisco Web Security Appliance (WSA) could allow an unauthenticated, remote attacker to log in to the FTP server of the device without a valid password. The attacker does need to have a valid username. The vulnerability is due to incorrect FTP user credential validation. An attacker could exploit this vulnerability by using FTP to connect to the management IP address of the targeted device. A successful exploit could allow the attacker to log in to the FTP server of the Cisco WSA without having a valid password. This vulnerability affects Cisco AsyncOS for WSA Software on both virtual and hardware appliances that are running any release of Cisco AsyncOS 10.5.1 for WSA Software. The device is vulnerable only if FTP is enabled on the management interface. FTP is disabled by default. Cisco Bug IDs: CSCvf74281.
CVE-2018-0093
A vulnerability in the web-based management interface of Cisco Web Security Appliance (WSA) could allow an unauthenticated, remote attacker to conduct a reflected cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device. The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the interface or allow the attacker to access sensitive browser-based information. Cisco Bug IDs: CSCvf37392.
CVE-2017-12303
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.
CVE-2017-6749
A vulnerability in the web-based management interface of Cisco Web Security Appliance (WSA) could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device. Affected Products: virtual and hardware versions of Cisco Web Security Appliance (WSA). More Information: CSCvd88865. Known Affected Releases: 10.1.0-204.
CVE-2017-6748
A vulnerability in the CLI parser of the Cisco Web Security Appliance (WSA) could allow an authenticated, local attacker to perform command injection and elevate privileges to root. The attacker must authenticate with valid operator-level or administrator-level credentials. Affected Products: virtual and hardware versions of Cisco Web Security Appliance (WSA). More Information: CSCvd88855. Known Affected Releases: 10.1.0-204. Known Fixed Releases: 10.5.1-270 10.1.1-234.
CVE-2017-6746
A vulnerability in the web interface of the Cisco Web Security Appliance (WSA) could allow an authenticated, remote attacker to perform command injection and elevate privileges to root. The attacker must authenticate with valid administrator credentials. Affected Products: Cisco AsyncOS Software 10.0 and later for WSA on both virtual and hardware appliances. More Information: CSCvd88862. Known Affected Releases: 10.1.0-204. Known Fixed Releases: 10.5.1-270 10.1.1-235.
CVE-2017-6750
A vulnerability in AsyncOS for the Cisco Web Security Appliance (WSA) could allow an unauthenticated, local attacker to log in to the device with the privileges of a limited user or an unauthenticated, remote attacker to authenticate to certain areas of the web GUI, aka a Static Credentials Vulnerability. Affected Products: virtual and hardware versions of Cisco Web Security Appliance (WSA). More Information: CSCve06124. Known Affected Releases: 10.1.0-204. Known Fixed Releases: 10.5.1-270.
CVE-2017-6751
A vulnerability in the web proxy functionality of the Cisco Web Security Appliance (WSA) could allow an unauthenticated, remote attacker to forward traffic from the web proxy interface of an affected device to the administrative management interface of an affected device, aka an Access Control Bypass Vulnerability. Affected Products: virtual and hardware versions of Cisco Web Security Appliance (WSA). More Information: CSCvd88863. Known Affected Releases: 10.1.0-204 9.0.0-485.
CVE-2017-3870
A vulnerability in the URL filtering feature of Cisco AsyncOS Software for Cisco Web Security Appliance (WSA) could allow an unauthenticated, remote attacker to bypass a configured URL filter rule. Affected Products: This vulnerability affects all releases prior to the first fixed release of Cisco AsyncOS Software for Cisco Web Security Appliance (WSA), both virtual and hardware appliances, that are configured with URL filters for email scanning. More Information: CSCvc69700. Known Affected Releases: 8.5.3-069 9.1.1-074 9.1.2-010.
CVE-2016-9212
A vulnerability in the Decrypt for End-User Notification configuration parameter of Cisco AsyncOS Software for Cisco Web Security Appliances could allow an unauthenticated, remote attacker to connect to a secure website over Secure Sockets Layer (SSL) or Transport Layer Security (TLS), even if the WSA is configured to block connections to the website. Affected Products: This vulnerability affects Cisco Web Security Appliances if the HTTPS decryption options are enabled and configured for the device to block connections to certain websites. More Information: CSCvb49012. Known Affected Releases: 9.0.1-162 9.1.1-074.
