CVSS v3.1 |
| The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. |
| A vulnerability in the web-based management interface of Cisco Expressway Series could allow an unauthenticated, remote attacker to redirect a user to a malicious web page.
This vulnerability is due to improper input validation of HTTP request parameters. An attacker could exploit this vulnerability by intercepting and modifying an HTTP request from a user. A successful exploit could allow the attacker to redirect the user to a malicious web page.
Note: Cisco Expressway Series refers to Cisco Expressway Control (Expressway-C) devices and Cisco Expressway Edge (Expressway-E) devices. |
| A vulnerability in the certificate validation of Cisco Expressway-C and Cisco TelePresence VCS could allow an unauthenticated, remote attacker to gain unauthorized access to sensitive data. The vulnerability is due to a lack of validation of the SSL server certificate that an affected device receives when it establishes a connection to a Cisco Unified Communications Manager device. An attacker could exploit this vulnerability by using a man-in-the-middle technique to intercept the traffic between the devices, and then using a self-signed certificate to impersonate the endpoint. A successful exploit could allow the attacker to view the intercepted traffic in clear text or alter the contents of the traffic.
Note: Cisco Expressway-E is not affected by this vulnerability.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. |
| A vulnerability in the REST API of Cisco Expressway Series and Cisco TelePresence VCS could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected system.
This vulnerability is due to insufficient CSRF protections for the web-based management interface of an affected system. An attacker could exploit this vulnerability by persuading a user of the REST API to follow a crafted link. A successful exploit could allow the attacker to cause the affected system to reload.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. |
| A vulnerability in the Session Initiation Protocol (SIP) on the Cisco TelePresence Video Communication Server (VCS) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on the targeted appliance. The vulnerability is due to excessive SIP traffic sent to the device. An attacker could exploit this vulnerability by transmitting large volumes of SIP traffic to the VCS. An exploit could allow the attacker to cause a complete DoS condition on the targeted system. Cisco Bug IDs: CSCve32897. |
| A vulnerability in the received packet parser of Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) software could allow an unauthenticated, remote attacker to cause a reload of the affected system, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient size validation of user-supplied data. An attacker could exploit this vulnerability by sending crafted H.224 data in Real-Time Transport Protocol (RTP) packets in an H.323 call. An exploit could allow the attacker to overflow a buffer in a cache that belongs to the received packet parser, which will result in a crash of the application, resulting in a DoS condition. All versions of Cisco Expressway Series Software and Cisco TelePresence VCS Software prior to version X8.8.2 are vulnerable. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. Cisco Bug IDs: CSCus99263. |
| A vulnerability in the cluster database (CDB) management component of Cisco Expressway Series Software and Cisco TelePresence Video Communication Server (VCS) Software could allow an authenticated, remote attacker to cause the CDB process on an affected system to restart unexpectedly, resulting in a temporary denial of service (DoS) condition. The vulnerability is due to incomplete input validation of URL requests by the REST API of the affected software. An attacker could exploit this vulnerability by sending a crafted URL to the REST API of the affected software on an affected system. A successful exploit could allow the attacker to cause the CDB process on the affected system to restart unexpectedly, resulting in a temporary DoS condition. Cisco Bug IDs: CSCve77571. |
| Cross-site scripting (XSS) vulnerability in Cisco TelePresence Video Communication Server (VCS) X8.5.1 allows remote attackers to inject arbitrary web script or HTML via a crafted URL, aka Bug ID CSCut27635. |
| Cisco TelePresence Video Communication Server (VCS) X8.1 through X8.7, as used in conjunction with Jabber Guest, allows remote attackers to obtain sensitive call-statistics information via a direct request to an unspecified URL, aka Bug ID CSCux73362. |
| Cisco TelePresence Video Communication Server (VCS) X8.5RC4 allows remote attackers to cause a denial of service (CPU consumption or device outage) via a crafted SDP parameter-negotiation request in an SDP session during a SIP connection, aka Bug ID CSCut42422. |
| Cisco TelePresence Video Communication Server (VCS) Expressway X8.6 allows remote authenticated users to bypass intended read-only restrictions and upload Tandberg Linux Package (TLP) files by visiting an administrative page, aka Bug ID CSCuw55651. |
| The administrative web interface in Cisco TelePresence Video Communication Server Expressway X8.5.2 allows remote authenticated users to execute arbitrary commands via crafted fields, aka Bug ID CSCuv12531. |
| The SIP IX implementation in Cisco TelePresence Video Communication Server (VCS) and Expressway Software before X8.1.1 allows remote attackers to cause a denial of service (device reload) via crafted SDP packets, aka Bug ID CSCuo42252. |
| The Session Description Protocol (SDP) implementation in Cisco TelePresence Video Communication Server (VCS) and Cisco Expressway before X8.2 and Cisco TelePresence Conductor before XC2.4 allows remote attackers to cause a denial of service (mishandled exception and device reload) via a crafted media description, aka Bug IDs CSCus96593 and CSCun73192. |
| Cisco TelePresence Video Communication Server (VCS) Expressway X8.5.2 allows remote attackers to cause a denial of service via invalid variables in an authentication packet, aka Bug ID CSCuv40469. |
| Cisco TelePresence Video Communication Server (VCS) X8.5.2 allows remote authenticated users to execute arbitrary commands in the context of the nobody user account via an unspecified web-page parameter, aka Bug ID CSCuv12333. |
| The Mobile and Remote Access (MRA) component in Cisco TelePresence Video Communication Server (VCS) X8.1 through X8.7 and Expressway X8.1 through X8.6 mishandles certificates, which allows remote attackers to bypass authentication via an arbitrary trusted certificate, aka Bug ID CSCuz64601. |
| Cisco TelePresence Video Communications Server (VCS) X8.x before X8.7.2 allows remote attackers to cause a denial of service (service disruption) via a crafted URI in a SIP header, aka Bug ID CSCuy43258. |
| Cisco TelePresence Video Communication Server (VCS) Expressway X8.5.1 and X8.5.2 allows local users to write to arbitrary files via an unspecified symlink attack, aka Bug ID CSCuv11969. |
| Cisco TelePresence Video Communication Server (VCS) and Cisco Expressway allow remote attackers to cause a denial of service (memory and CPU consumption, and partial outage) via crafted SIP packets, aka Bug ID CSCur12473. |
