Published: 14 December 2022
Summary
CVE-2022-37155 is a high-severity Code Injection (CWE-94) vulnerability in Spip Spip. Its CVSS base score is 8.8 (High).
Operationally, ranked in the top 8.9% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
CVE-2022-37155 is a remote code execution vulnerability affecting SPIP versions 3.1.13 through 4.1.2. It stems from improper handling of the _oups parameter and is associated with CWE-94 code injection, carrying a CVSS 3.1 score of 8.8 that reflects network-accessible exploitation with low attack complexity.
Remote authenticated users can supply a crafted _oups value to execute arbitrary code on the server, resulting in full compromise of confidentiality, integrity, and availability without user interaction.
Official SPIP advisories recommend immediate upgrade to the patched releases 4.1.5, 4.0.8, or 3.2.16 to close the flaw.
EPSS for the CVE reached a peak of 0.0790 after disclosure before settling at the current value of 0.0620, indicating a modest but noticeable rise in exploitation interest post-publication.

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.
