The vulnerabilities tracked by CVE-2026-76481 are related to issues concerning improper handling of exceptional conditions that are grouped under the Common Weakness Enumeration (CWE) Pillar CWE-703. |
| Apache Log4j2 2.0-beta9 through 2.15.0 (excluding security releases 2.12.2, 2.12.3, and 2.3.1) JNDI features used in configuration, log messages, and parameters do not protect against attacker controlled LDAP and other JNDI related endpoints. An attacker who can control log messages or log message parameters can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled. From log4j 2.15.0, this behavior has been disabled by default. From version 2.16.0 (along with 2.12.2, 2.12.3, and 2.3.1), this functionality has been completely removed. Note that this vulnerability is specific to log4j-core and does not affect log4net, log4cxx, or other Apache Logging Services projects. |
| A vulnerability in Cisco Unified Communications Manager (Unified CM) and Cisco Unified Communications Manager Session Management Edition (Unified CM SME) could allow an unauthenticated, remote attacker to conduct server-side request forgery (SSRF) attacks through an affected device.
This vulnerability is due to improper input validation for specific HTTP requests. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. A successful exploit could allow the attacker to write files to the underlying operating system that could be used later to elevate to root.
Note: Cisco has assigned this security advisory a Security Impact Rating (SIR) of Critical rather than High as the score indicates. The reason is that exploitation of this vulnerability could result in an attacker elevating privileges to root.
Note: To exploit this vulnerability, the WebDialer service must be enabled. WebDialer is disabled by default. |
| Cisco Unified Communications Manager (CUCM, formerly CallManager) 5.1 before 5.1(2), and Unified CallManager 5.0, allow remote attackers to cause a denial of service (kernel panic) via a flood of SIP INVITE messages to UDP port 5060, which triggers resource exhaustion, aka CSCsi75822. |
| Buffer overflow in the Centralized TFTP File Locator Service in Cisco Unified Communications Manager (CUCM, formerly CallManager) 5.1 before 5.1(3), and Unified CallManager 5.0, allows remote attackers to execute arbitrary code or cause a denial of service via unspecified vectors involving the processing of filenames, aka CSCsh47712. |

| Cisco Unified Communications Manager (CUCM, formerly CallManager) and Unified Presence Server (CUPS) allow remote attackers to obtain sensitive information via unspecified vectors that reveal the SNMP community strings and configuration settings, aka (1) CSCsj20668 and (2) CSCsj25962. |
| The Certificate Authority Proxy Function (CAPF) service in Cisco Unified Communications Manager (CUCM) 4.1 before 4.1(3)SR7, 4.2 before 4.2(3)SR4, and 4.3 before 4.3(2) allows remote attackers to cause a denial of service (service crash) via malformed network traffic, aka Bug ID CSCsk46770. |
| Cisco Unified Communications Manager (aka CUCM, formerly CallManager) before 6.1(1) allows remote attackers to cause a denial of service (voice-services outage) via a malformed header in a SIP message, aka Bug ID CSCsi46466. |
| Unspecified vulnerability in Cisco Unified Communications Manager (CUCM) 5.0, 5.1, and 6.0, and IOS 12.0 through 12.4, allows remote attackers to execute arbitrary code via a malformed SIP packet, aka CSCsi80102. |
