A vulnerability in the web-based management interface of Cisco TelePresence Management Suite (TMS) could allow a low-privileged, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface.
This vulnerability is due to insufficient input validation by the web-based management interface. An attacker could exploit this vulnerability by inserting malicious data in a specific data field in the interface. 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.
A vulnerability in the web-based management interface of Cisco AsyncOS for Cisco Content Security Management Appliance (SMA) could allow an unauthenticated, remote attacker to obtain sensitive network information.
A vulnerability in the web UI of Cisco APIC could allow an authenticated, remote attacker to perform a stored XSS attack on an affected system. To exploit this vulnerability, the attacker must have valid administrative credentials.
This vulnerability is due to improper input validation in the web UI. An authenticated attacker could exploit this vulnerability by injecting malicious code into specific pages of the web UI. A successful exploit could allow the attacker to execute arbitrary script code in the context of the web UI or access sensitive, browser-based information.
A vulnerability in the CLI of Cisco APIC could allow an authenticated, local attacker to execute arbitrary commands as root on the underlying operating system of an affected device. To exploit this vulnerability, the attacker must have valid administrative credentials.
This vulnerability is due to insufficient validation of arguments that are passed to specific CLI commands. An attacker could exploit this vulnerability by including crafted input as the argument of an affected CLI command. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system with the privileges of root.
A vulnerability in the implementation of the internal system processes of Cisco APIC could allow an authenticated, local attacker to access sensitive information on an affected device. To exploit this vulnerability, the attacker must have valid administrative credentials.
This vulnerability is due to insufficient masking of sensitive information that is displayed through system CLI commands. An attacker could exploit this vulnerability by using reconnaissance techniques at the device CLI. A successful exploit could allow the attacker to access sensitive information on an affected device that could be used for additional attacks.
A vulnerability in the system file permission handling of Cisco APIC could allow an authenticated, local attacker to overwrite critical system files, which could cause a DoS condition. To exploit this vulnerability, the attacker must have valid administrative credentials.
This vulnerability is due to a race condition with handling system files. An attacker could exploit this vulnerability by doing specific operations on the file system. A successful exploit could allow the attacker to overwrite system files, which could lead to the device being in an inconsistent state and cause a DoS condition.
OpenH264 is a free license codec library which supports H.264 encoding and decoding. A vulnerability in the decoding functions of OpenH264 codec library could allow a remote, unauthenticated attacker to trigger a heap overflow. This vulnerability is due to a race condition between a Sequence Parameter Set (SPS) memory allocation and a subsequent non Instantaneous Decoder Refresh (non-IDR) Network Abstraction Layer (NAL) unit memory usage. An attacker could exploit this vulnerability by crafting a malicious bitstream and tricking a victim user into processing an arbitrary video containing the malicious bistream. An exploit could allow the attacker to cause an unexpected crash in the victim's user decoding client and, possibly, perform arbitrary commands on the victim's host by abusing the heap overflow. This vulnerability affects OpenH264 2.5.0 and earlier releases. Both Scalable Video Coding (SVC) mode and Advanced Video Coding (AVC) mode are affected by this vulnerability. OpenH264 software releases 2.6.0 and later contained the fix for this vulnerability. Users are advised to upgrade. There are no known workarounds for this vulnerability.

A vulnerability in the debug shell of Cisco Video Phone 8875 and Cisco Desk Phone 9800 Series could allow an authenticated, local attacker to access sensitive information on an affected device. To exploit this vulnerability, the attacker must have valid administrative credentials with SSH access on the affected device. SSH access is disabled by default.
This vulnerability is due to insufficient validation of user-supplied input by the debug shell of an affected device. An attacker could exploit this vulnerability by sending a crafted SSH client command to the CLI. A successful exploit could allow the attacker to access sensitive information on the underlying operating system.
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.
A vulnerability in the uninstaller component of Cisco AnyConnect Secure Mobility Client for Mac OS could allow an authenticated, local attacker to corrupt the content of any file in the filesystem.
The vulnerability is due to the incorrect handling of directory paths. An attacker could exploit this vulnerability by creating a symbolic link (symlink) to a target file on a specific path. A successful exploit could allow the attacker to corrupt the contents of the file. If the file is a critical systems file, the exploit could lead to a denial of service condition. To exploit this vulnerability, the attacker would need to have valid credentials on the system.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
