CVE-2026-6715
CriticalCVSS 9.8Summary
IBM Concert 1.0 through 3.0.1.1 allows an attacker to supply crafted input that is incorporated into an operating system command without adequate validation or sanitization. Successful exploitation allows remote attackers to execute arbitrary commands on the underlying operating system with the privileges of the affected service.
Risk Assessment
An attacker could take control of the system, execute arbitrary commands, and access data and resources with the privileges of the IBM Concert service. This poses a serious risk to confidentiality, integrity, and availability.
Recommendation
Update IBM Concert to a version later than 3.0.1.1 that contains the fix, and restrict network access to the service to trusted sources.
Other vulnerabilities in IBM Concert
See all- CVE-2025-33015High
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.
- CVE-2026-15266Critical
IBM Concert 1.0 through 3.0.1.1 contains components that allow potentially unsafe command execution, which could be exploited to run arbitrary system commands on the host.
- CVE-2026-6928Critical
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.
- CVE-2026-6730Critical
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.
- CVE-2026-6721Critical
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.
- CVE-2026-17472Critical
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.
- CVE-2026-3627Critical
IBM Concert versions 1.0.0 through 2.3.1 are vulnerable to SQL injection. A remote attacker could send specially crafted SQL statements, potentially allowing viewing, adding, modifying, or deleting information in the back-end database.
- CVE-2026-6719High
IBM Concert 1.0 through 3.0.0 uses weaker than expected cryptographic algorithms. This could allow an attacker to decrypt highly sensitive information.
- CVE-2026-4413Medium
IBM Concert 1.0 through 3.0.0 is vulnerable to cross-site scripting. This allows an unauthenticated attacker to embed arbitrary JavaScript code in the Web UI, altering intended functionality and potentially leading to credential disclosure within a trusted session.
- CVE-2026-4405Medium
IBM Concert 1.0 through 3.0.0 allows web page cache to be stored locally, which can be read by another user on the system.
