CVE-2023-46042
Published: 19 October 2023
Summary
CVE-2023-46042 is a critical-severity Code Injection (CWE-94) vulnerability in Get-Simple Getsimplecms. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 1.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
GetSimpleCMS version 3.4.0a contains a code injection vulnerability tracked as CVE-2023-46042. The flaw resides in the handling of input passed to the phpinfo() function and is classified under CWE-94, enabling an unauthenticated attacker to supply a crafted payload that results in arbitrary code execution. The issue carries a CVSS 3.1 score of 9.8, reflecting network attack vector, low complexity, and no required privileges or user interaction.
An attacker with network access can send a malicious request directly to the affected phpinfo() endpoint. Successful exploitation grants the ability to execute arbitrary code on the server, which in turn provides full control over the confidentiality, integrity, and availability of the application and underlying system.
The two referenced GitHub entries describe a related file-write primitive in the same product but supply no official patch information or mitigation guidance. The EPSS score has remained at its recorded peak of 0.6824, indicating sustained exploitation interest since disclosure without a subsequent upward trajectory.

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.
Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.
Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.
Validates inputs used in dynamic code generation to block injected directives.
Directly prevents execution of attacker-supplied code written into data memory regions.
