IBM Concert Software versions 1.0.0 through 1.1.0 are vulnerable due to improper cross-origin resource sharing (CORS) configurations. This flaw could allow attackers to perform privileged actions as the domain name is not restricted to trusted domains. Users should be aware of the potential risks associated with this vulnerability.
Details
| Severity | Base Score | CVE |
|---|---|---|
| MEDIUM | 5.4 | CVE-2025-27909 |
Exploitation
To exploit this vulnerability, an attacker could craft a malicious request that takes advantage of the CORS misconfiguration. By sending requests from an untrusted domain, the attacker could perform actions that require higher privileges, potentially compromising sensitive data or functionality within the application.
Affected Products
- IBM Concert Software 1.0.0: Initial release vulnerable to CORS issues.
- IBM Concert Software 1.1.0: Update that still retains the CORS vulnerability.
Mitigation
To mitigate this vulnerability, it is recommended that users restrict CORS settings to only allow trusted domains. Additionally, updating to a patched version of the software, if available, is crucial to ensure that the application is secure against this type of attack.
