CVE-2023-38739 is a medium-severity CSRF (CWE-352) vulnerability in Ibm Sterling B2B Integrator. Its CVSS base score is 4.3 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 31.4th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SC-23 (Session Authenticity) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2023-38739 is a cross-site request forgery (CSRF) vulnerability, mapped to CWE-352, in IBM Sterling B2B Integrator versions 6.0.0.0 through 6.1.2.5 and 6.2.0.0 through 6.2.0.3. Published on 2025-01-31, it carries a CVSS v3.1 base score of 4.3 (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N), indicating medium severity with network accessibility, low attack complexity, no required privileges, user interaction needed, and low integrity impact.
An unauthenticated attacker can exploit this by crafting a malicious webpage or link that, when visited by an authenticated user, triggers unauthorized requests to the vulnerable IBM Sterling B2B Integrator instance. This allows the attacker to execute malicious actions on behalf of the trusted user, such as modifying application state or performing unintended operations, relying on the absence of proper CSRF protections.
IBM's security advisory at https://www.ibm.com/support/pages/node/7182004 provides details on the vulnerability, including recommended patches and mitigation guidance for affected versions. Security practitioners should review this resource promptly to apply updates and implement defenses like CSRF tokens.

SI-2 directly addresses the CVE by requiring identification, reporting, and correction of the specific CSRF flaw through vendor-recommended patches.
SC-23 enforces session authenticity mechanisms like CSRF tokens to prevent attackers from executing unauthorized actions on behalf of authenticated users.
SI-10 requires validation of information inputs, including CSRF tokens or origin headers, to block forged requests exploiting the vulnerability.
