Published: 20 September 2022
Summary
CVE-2022-3242 is a medium-severity Code Injection (CWE-94) vulnerability in Microweber Microweber. Its CVSS base score is 6.1 (Medium).
Operationally, ranked in the top 4.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
The vulnerability is a code injection flaw, also referenced under CWE-94 and CWE-79, affecting the Microweber GitHub repository in versions prior to 1.3.2. It received a CVSS 3.1 score of 6.1 with the vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N, indicating remote exploitability without authentication but requiring user interaction and producing limited impacts to confidentiality and integrity with changed scope.
An unauthenticated attacker can supply crafted input that triggers code injection when processed by the application. Successful exploitation allows the attacker to execute arbitrary code or inject scripts in the context of a victim's session, potentially leading to unauthorized actions or data exposure within the affected Microweber instance.
The referenced commit 68f0721571653db865a5fa01c7986642c82e919c in the microweber/microweber repository resolves the issue, and the associated huntr.dev bounty report provides further details on the fix. Mitigation consists of upgrading to version 1.3.2 or later.
The EPSS score remains flat at a peak and current value of 0.1979 with no material increase after disclosure.

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.
Validates web inputs to reject script-related content that could produce XSS.
Penetration testing submits XSS payloads to web applications, detecting cross-site scripting flaws for subsequent remediation.
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.
Output validation against expected content can reject or sanitize script content in generated web pages, reducing XSS exploitability.
Directly prevents execution of attacker-supplied code written into data memory regions.
