CVE-2023-29923
Published: 19 April 2023
Summary
CVE-2023-29923 is a medium-severity Incorrect Default Permissions (CWE-276) vulnerability in Powerjob Powerjob. Its CVSS base score is 5.3 (Medium).
Operationally, ranked in the top 0.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
PowerJob version 4.3.1 contains an insecure permissions vulnerability, tracked as CWE-276, that affects the list job interface. The flaw received a CVSS 3.1 base score of 5.3, reflecting network attack vector, low complexity, and no required authentication or user interaction, resulting in partial disclosure of job-related information.
An unauthenticated remote attacker can send requests directly to the list job endpoint and retrieve limited job data that should otherwise be restricted. This exposure occurs because the interface does not enforce proper access controls, allowing any network-reachable party to observe job listings without credentials.
The associated GitHub issue references provide the primary public discussion of the flaw. The EPSS score reached a peak of 0.8544 shortly after disclosure and has remained at that level, indicating sustained exploitation interest rather than a gradual increase from a low baseline.

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.
Access control policy can specify and enforce secure default permissions for resources.
Guides setting of default permissions to the minimum required level.
Establishes requirements for appropriate default permissions on system resources as part of configuration management.
Baseline establishment and updates on install/upgrade ensure correct default permissions rather than insecure ones.
Requiring the most restrictive settings instead of defaults prevents incorrect default permissions on resources.
Requires documented processes that include setting and maintaining correct default permissions for configuration items.
Requires addressing secure default permissions in physical and environmental protection controls.
Tailoring explicitly overrides or scopes default permission assignments in the baseline to match the system's actual risk and operational needs.
