CVE-2014-6287
RCE in Rejetto Http File Server 2.3 – 2.3c
Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2014-6287 is a critical-severity Code Injection (CWE-94) vulnerability in Rejetto Http File Server. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Junk Data (T1001.001); ranked in the top 0.1% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
The vulnerability is a code injection flaw (CWE-94) in the findMacroMarker function within parserLib.pas of Rejetto HTTP File Server (HFS or HttpFileServer) versions 2.3x prior to 2.3c. It is triggered when a %00 sequence is supplied in a search action, enabling execution of arbitrary programs on the underlying host. The issue carries a CVSS 3.1 base score of 9.8.
Unauthenticated remote attackers can exploit the flaw over the network by sending a crafted search request containing the null-byte sequence. Successful exploitation grants the ability to run arbitrary programs with the privileges of the HFS process, resulting in full compromise of confidentiality, integrity, and availability.
Public exploit code targeting this issue has been published repeatedly on PacketStorm, and the vulnerability is tracked in the CERT Vulnerability Note VU#251276. The supplied description indicates that upgrading to version 2.3c or later eliminates the affected code path.

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.
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.

PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).
PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.
