Memory leak in Cisco Unified Communications Manager IM and Presence Service before 8.6(5)SU1 and 9.x before 9.1(2), and Cisco Unified Presence, allows remote attackers to cause a denial of service (memory and CPU consumption) by making many TCP connections to port (1) 5060 or (2) 5061, aka Bug ID CSCud84959.

Cross-site request forgery (CSRF) vulnerability in the User WebDialer page in Cisco Unified Communications Manager (Unified CM) allows remote attackers to hijack the authentication of arbitrary users for requests that dial calls, aka Bug ID CSCui13028.

Multiple cross-site request forgery (CSRF) vulnerabilities in Cisco Unified Communications Manager (Unified CM) allow remote attackers to hijack the authentication of arbitrary users for requests that perform arbitrary Unified CM operations, aka Bug ID CSCui13033.

The web portal in Cisco Unified Communications Manager (Unified CM) allows remote authenticated users to obtain sensitive stack-trace information via unspecified vectors that trigger a stack exception, aka Bug ID CSCug34854.

Cisco Unified Communications Manager (CUCM) 7.1(x) through 9.1(2) and the IM & Presence Service in Cisco Unified Presence Server through 9.1(2) use the same CTI and database-encryption key across different customers' installations, which makes it easier for context-dependent attackers to defeat cryptographic protection mechanisms by leveraging knowledge of this key, aka Bug IDs CSCsc69187 and CSCui01756. NOTE: the vendor has provided a statement that the "hard-coded static encryption key is considered a hardening issue rather than a vulnerability, and as such, has a CVSS score of 0/0."

Untrusted search path vulnerability in Cisco Unified Communications Manager (CUCM) 7.1(x) through 9.1(1a) allows local users to gain privileges by leveraging unspecified file-permission and environment-variable issues for privileged programs, aka Bug ID CSCui02242.

Untrusted search path vulnerability in Cisco Unified Communications Manager (CUCM) 7.1(x) through 9.1(1a) allows local users to gain privileges by leveraging unspecified file-permission and environment-variable issues for privileged programs, aka Bug ID CSCui02276.

SQL injection vulnerability in Cisco Unified Communications Manager (CUCM) 7.1(x) through 9.1(2) allows remote authenticated users to execute arbitrary SQL commands via unspecified vectors, aka Bug ID CSCuh81766.

SQL injection vulnerability in Cisco Unified Communications Manager (CUCM) 7.1(x) through 9.1(1a) allows remote attackers to execute arbitrary SQL commands via unspecified vectors, leading to discovery of encrypted credentials by leveraging metadata, aka Bug ID CSCuh01051.

Multiple untrusted search path vulnerabilities in Cisco Unified Communications Manager (CUCM) 7.1(x) through 9.1(1a) allow local users to gain privileges by leveraging unspecified file-permission and environment-variable issues for privileged programs, aka Bug ID CSCuh73454.

An unspecified function in Cisco Unified Communications Manager (CUCM) 7.1(x) through 9.1(2) allows remote authenticated users to execute arbitrary commands via unknown vectors, aka Bug ID CSCuh73440.

Cross-site request forgery (CSRF) vulnerability in the Unified Serviceability component in Cisco Unified Communications Manager (CUCM) allows remote attackers to hijack the authentication of arbitrary users for requests that perform Unified Serviceability actions, aka Bug ID CSCuh10298.

Cisco Unified Communications Manager (CUCM) does not properly limit the rate of authentication attempts, which allows remote attackers to cause a denial of service (application slowdown) via a series of requests, aka Bug ID CSCud39515.

The command-line interface in Cisco Unified Communications Manager (CUCM) does not properly validate input, which allows local users to read arbitrary files via unspecified vectors, aka Bug ID CSCue25770.

Cisco Unified Communications Manager (CUCM) 8.6 before 8.6(2a)su2, 8.6 BE3k before 8.6(4) BE3k, and 9.x before 9.0(1) allows remote attackers to cause a denial of service (CPU consumption and GUI and voice outages) via malformed packets to unused UDP ports, aka Bug ID CSCtx43337.

SQL injection vulnerability in Cisco Unified Communications Manager (CUCM) with software 6.x and 7.x before 7.1(5b)su5, 8.0 before 8.0(3a)su3, and 8.5 and 8.6 before 8.6(2a)su1 and Cisco Business Edition 3000 with software before 8.6.3 and 5000 and 6000 with software before 8.6(2a)su1 allows remote attackers to execute arbitrary SQL commands via a crafted SCCP registration, aka Bug ID CSCtu73538.
