A vulnerability in the web-based interface of multiple Cisco Unified Communications products could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based interface of the affected software. The vulnerability is due to insufficient validation of user-supplied input by the web-based interface of the affected software. 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 affected interface or access sensitive browser-based information.

A vulnerability in the authentication service of the Cisco Unified Communications Manager IM and Presence (Unified CM IM&P) Service, Cisco TelePresence Video Communication Server (VCS), and Cisco Expressway Series could allow an unauthenticated, remote attacker to cause a service outage for users attempting to authenticate, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient controls for specific memory operations. An attacker could exploit this vulnerability by sending a malformed Extensible Messaging and Presence Protocol (XMPP) authentication request to an affected system. A successful exploit could allow the attacker to cause an unexpected restart of the authentication service, preventing users from successfully authenticating. Exploitation of this vulnerability does not impact users who were authenticated prior to an attack. • http://www.securityfocus.com/bid/108615 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190605-cucm-imp-dos • CWE-20: Improper Input Validation •

A vulnerability in the web interface of Cisco Emergency Responder, Cisco Unified Communications Manager, Cisco Unified Communications Manager IM & Presence Service, and Cisco Unity Connection could allow an authenticated, remote attacker to redirect a user to a malicious web page. The vulnerability is due to improper input validation of the parameters of an HTTP request. An attacker could exploit this vulnerability by crafting an HTTP request that causes the web interface to redirect a request to a specific malicious URL. This type of vulnerability is known as an open redirect attack and is used in phishing attacks that get users to unknowingly visit malicious sites. Una vulnerabilidad en la interfaz web de Cisco Emergency Responder, Cisco Unified Communications Manager, Cisco Unified Communications Manager IM Presence Service y Cisco Unity Connection podría permitir que un atacante remoto autenticado redirija a un usuario a una página web maliciosa. • http://www.securitytracker.com/id/1041780 http://www.securitytracker.com/id/1041789 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20181003-er-ucm-redirect • CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •

A vulnerability in the XCP Router service of the Cisco Unified Communications Manager IM & Presence Service (CUCM IM&P) and the Cisco TelePresence Video Communication Server (VCS) and Expressway could allow an unauthenticated, remote attacker to cause a temporary service outage for all IM&P users, resulting in a denial of service (DoS) condition. The vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by sending a malicious IPv4 or IPv6 packet to an affected device on TCP port 7400. An exploit could allow the attacker to overread a buffer, resulting in a crash and restart of the XCP Router service.

CVSS: 6.1EPSS: 0%CPEs: 2EXPL: 0

A vulnerability in the web framework of the Cisco Unified Communications Manager IM and Presence Service software could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against the user of the web interface of an affected system. The vulnerability is due to insufficient input validation of certain parameters passed to the web server. An attacker could exploit this vulnerability by convincing the user to access a malicious link or by intercepting the user request and injecting certain malicious code. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected site or allow the attacker to access sensitive browser-based information.
