Published: 30 June 2023
Summary
CVE-2023-36347 is a high-severity Missing Authentication for Critical Function (CWE-306) vulnerability in Codekop Codekop. Its CVSS base score is 7.5 (High).
Operationally, ranked in the top 0.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
A broken authentication mechanism affects the excel.php endpoint in POS Codekop version 2.0. The flaw, tracked as CVE-2023-36347 and assigned CWE-306, permits direct access to the endpoint without any credentials, resulting in a CVSS 3.1 score of 7.5 that reflects network-exploitable confidentiality exposure.
Unauthenticated remote attackers can retrieve selling data by simply requesting the endpoint. The attack requires no user interaction or privileges and produces high impact on data confidentiality while leaving integrity and availability unaffected.
The provided references consist of a technical write-up and demonstration video that detail the endpoint exposure but contain no information on patches or mitigation steps. The associated EPSS score has remained elevated near its peak value of 0.8448 with a current reading of 0.8211.

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.
Requires established identification and authentication to unlock, mitigating missing authentication for continued system access.
Requiring identification and rationale for actions allowed without authentication ensures critical functions are not left unprotected by forcing review of authentication requirements.
Authorizing mobile device connections to organizational systems ensures authentication is performed for this critical access function.
Guarantees critical functions are protected by mandatory invocation of the access control mechanism.
Auditing sessions makes it possible to detect access to critical functions without required authentication.
The assessment process confirms authentication is present and effective for critical functions, preventing exploitation from missing authentication.
Certification assesses that critical functions have required authentication controls in place.
Disabling non-essential functions and services eliminates the need to secure them, reducing exposure from missing authentication on unnecessary components.
