CVE-2023-26546
Published: 02 May 2023
Summary
CVE-2023-26546 is a high-severity Code Injection (CWE-94) vulnerability in Echa.Europa Iuclid. Its CVSS base score is 8.8 (High).
Operationally, ranked in the top 9.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
European Chemicals Agency IUCLID versions before 6.27.6 contain a server-side template injection vulnerability that permits remote code execution when an authenticated user uploads a crafted template file. The flaw is tracked under CWE-94 and carries a CVSS 3.1 base score of 8.8, reflecting network attack vector, low complexity, and high impact on confidentiality, integrity, and availability.
Exploitation requires an account with template-manager permission. An attacker in that role can submit a malicious template that is processed by the server, resulting in arbitrary code execution within the IUCLID application context.
The vendor addressed the issue in IUCLID 6.27.6, as documented in the release note published on the official IUCLID site; organizations are advised to upgrade to that version or later and to restrict template-manager rights to trusted personnel.
EPSS for the CVE rose from a low baseline to a recorded peak of 0.0832, indicating measurable post-disclosure interest that warrants renewed attention even though current probability sits at 0.0549.

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.
