CVE-2022-41544
Published: 18 October 2022
Summary
CVE-2022-41544 is a critical-severity Code Injection (CWE-94) vulnerability in Get-Simple Getsimple Cms. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 2.5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
GetSimple CMS version 3.3.16 contains a remote code execution vulnerability that stems from insufficient validation of the edited_file parameter within admin/theme-edit.php. The flaw is tracked under CVE-2022-41544 with a CVSS score of 9.8 and is associated with CWE-94 code injection, allowing an attacker to supply crafted input that results in arbitrary code execution on the server.
Unauthenticated remote attackers can exploit the issue over the network without any user interaction or credentials. Successful exploitation grants full control over the affected application, enabling attackers to read, modify, or delete data and potentially take over the underlying host.
Public references include a PacketStorm entry describing shell-upload techniques against the same parameter and a corresponding GitHub issue in the GetSimpleCMS repository; neither source details official patches or configuration workarounds.
EPSS for the vulnerability rose from a low baseline to a peak of 0.6380, indicating increased exploitation interest after disclosure before receding to the current value of 0.4103.

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.
