Redhat Enterprise Linux Eus 7.4 … 7.7
Raw vector
CVSS:3.1/AV:N/AC:H/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-2017-12615 is a high-severity Unrestricted Upload of File with Dangerous Type (CWE-434) vulnerability in Redhat Enterprise Linux Eus. Its CVSS base score is 8.1 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Data Obfuscation (T1001); ranked in the top 0.0% 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 tracked as CVE-2017-12615 affects Apache Tomcat versions 7.0.0 through 7.0.79 running on Windows when the DefaultServlet is configured with its readonly initialization parameter set to false, enabling HTTP PUT requests. This configuration permits an attacker to upload a JSP file through a specially crafted request; once uploaded, the JSP can be accessed and executed by the server, resulting in arbitrary code execution. The issue is classified under CWE-434 and carries a CVSS 3.1 score of 8.1.
An unauthenticated remote attacker can exploit the flaw over the network by sending the crafted PUT request to upload a malicious JSP payload and then invoking it to execute code. Successful exploitation grants full control over the affected Tomcat instance, impacting confidentiality, integrity, and availability, although the attack requires the non-default PUT capability to be enabled and therefore receives a high attack-complexity rating.
Red Hat has published errata RHSA-2017:3080 and RHSA-2017:3081 that address the issue for supported products; additional details appear in vendor trackers such as SecurityFocus and SecurityTracker.

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.
Requiring identifiable owners for portable devices reduces the attack surface for unrestricted uploads of dangerous file types via anonymous media.
Dangerous file uploads can be detonated in the chamber to determine malice before any production write or execution occurs.
Prevents unrestricted writing of arbitrary or malicious firmware by keeping hardware write-protect enabled except under tightly controlled manual procedures.
Scans files from external sources on download/open/execute, blocking unrestricted uploads of dangerous file types.

Hardened configuration baselines can enforce allowed file types and processing rules.
Restricting execution of unauthorized software directly blocks dangerous uploaded files from running.
Secure development practices include input validation and file-type restrictions that prevent this weakness.
