Summary

CVE-2023-22889 is a critical-severity Code Injection (CWE-94) vulnerability in Smartbear Zephyr Enterprise. Its CVSS base score is 9.8 (Critical).

Operationally, ranked in the top 8.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

Deeper analysis

SmartBear Zephyr Enterprise through version 7.15.0 contains a code injection flaw (CWE-94) that arises when the application processes user-defined input during report generation. The affected component fails to properly sanitize or validate this input, resulting in a remotely exploitable condition rated at CVSS 9.8 with network attack vector, no authentication, and no user interaction required.

An unauthenticated attacker with network access can supply crafted input to trigger remote code execution, granting full confidentiality, integrity, and availability impact on the server. The published description explicitly states that unauthenticated users can achieve this outcome.

The vendor has published advisory information at https://smartbear.com/security/cve/. The associated EPSS score remains flat at 0.0634 with no material increase after disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-94

Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.

addresses: CWE-94

Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.

addresses: CWE-94

Validates inputs used in dynamic code generation to block injected directives.

addresses: CWE-94

Directly prevents execution of attacker-supplied code written into data memory regions.
