CVE-2026-6925

IBM Concert 1.0.0 through 3.0.0 invokes OS commands without fully qualifying executable paths or adequately restricting search path resolution. An attacker with local system access can manipulate the search path environment to execute untrusted or malicious code.

IBM Concert 1.0.0 through 3.0.0 has a double free vulnerability due to incorrect memory management. A local attacker can exploit this flaw to corrupt heap memory and execute arbitrary code in the context of the affected process.

IBM Concert versions 1.0.0 through 3.0.0 is vulnerable to improper access control, allowing unauthorized modification of application files.

IBM Concert 1.0.0 through 3.0.0 could allow an unauthorized user to inject data into log messages due to improper neutralization of special elements when written to log files.

IBM Concert versions 1.0.0 through 3.0.0 could allow a remote attacker to obtain sensitive information when a detailed technical error message is returned in the browser. This information could be used in further attacks against the system.

IBM Concert versions 1.0.0 through 2.1.0 is vulnerable to malicious file upload due to lack of content validation for files uploaded to the web interface. An attacker could exploit this to upload harmful files.

IBM Concert versions 1.0.0 through 3.0.0 references or accesses memory after it has been freed (use-after-free). An attacker who can influence program execution or input may exploit this condition to corrupt memory, cause application crashes, or execute arbitrary code.

IBM Concert versions 1.0.0 through 3.0.0 is vulnerable to a buffer overflow caused by improper bounds checking. A local user could overflow the buffer and execute arbitrary code on the system.

IBM Concert versions 1.0.0 through 3.0.0 allows an unauthenticated remote attacker to supply specially crafted input that is incorporated into OS commands, resulting in arbitrary command execution. Successful exploitation allows remote code execution with the privileges of the affected application.

IBM Concert 1.0.0 through 3.0.0 could allow a remote authenticated attacker to access or modify unauthorized resources due to the use of wildcards in RBAC permission definitions.
