Horizon Alert
Summary of the vulnerability and why it matters
IBM Concert software has a weakness that could allow a local user to run unauthorized code on a system. The primary concern is confirming if this software is in use and potentially exposed.
- Local access allows code execution if vulnerable.
- Understand potential for unauthorized code execution.
- Confirm relevance and exposure within your environment.
Attack Path
How an attacker could exploit the issue
An attacker with local access to a system running IBM Concert could exploit a buffer overflow vulnerability. This occurs due to insufficient checks on data boundaries, allowing an attacker to overwrite memory. Successful exploitation could lead to arbitrary code execution on the affected system.
- Requires local user access.
- Exploits improper bounds checking.
- Enables arbitrary code execution.
Live Threat
Current exploitation, exposure, and threat context
A local user could exploit a buffer overflow vulnerability in IBM Concert to execute arbitrary code. This could impact system integrity and confidentiality when the software is running and accessible locally.
- System data and services.
- Local user overflows buffer.
- Arbitrary code execution possible.
Operational Fix
Recommended remediation, mitigation, and detection steps
IBM Concert, when deployed on Linux, presents a local privilege escalation risk that could allow an attacker to execute arbitrary code. Owners of affected Linux systems and the administrators responsible for IBM Concert should initiate an inventory of existing deployments. Confirming business criticality and identifying the specific accountable teams for these systems will be the immediate next step before planning remediation.
- Identify affected Linux systems and owners.
- Verify business criticality and reachability.
- Plan remediation based on confirmed risk.
