CVE-2023-29919
Published: 23 May 2023
Summary
CVE-2023-29919 is a critical-severity Incorrect Default Permissions (CWE-276) vulnerability in Contec Solarview Compact Firmware. Its CVSS base score is 9.1 (Critical).
Operationally, ranked in the top 0.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
SolarView Compact versions 6.0 and earlier contain an insecure permissions vulnerability tracked as CVE-2023-29919 and CWE-276. The flaw stems from unrestricted access to texteditor.php, which permits any file on the underlying server to be read or written without authentication. The issue carries a CVSS 3.1 base score of 9.1 reflecting network attack vector, low complexity, and high impact on confidentiality and integrity.
An unauthenticated remote attacker can directly invoke the affected script to retrieve or alter arbitrary files, enabling credential theft, configuration changes, or deployment of malicious content on the host. No user interaction or privileges are required for successful exploitation.
The EPSS score stands at 0.9271 with an identical recorded peak, indicating sustained exploitation interest since disclosure. Public references consist of a proof-of-concept repository and the vendor site, but no official patch or mitigation guidance is supplied in the available data.

Likely Mitigating Controls AI
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.
