Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly mitigates unrestricted file uploads by enforcing validation of file types, extensions, and content at upload points to prevent dangerous files from being accepted.

SI-2 Flaw Remediation good match

prevent

Requires timely patching of the specific arbitrary file upload flaw as fixed in Census CSWeb 8.1.0 to eliminate the vulnerability.

SI-3 Malicious Code Protection good match

preventdetect

Deploys malicious code protection at system entry points like file uploads to scan and block executable or dangerous files leading to RCE.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

T1068 Exploitation for Privilege Escalation Privilege Escalation

Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.

attack.mitre.org →

Why these techniques?

Arbitrary file upload in public-facing web application enables exploitation for initial access (T1190) and privilege escalation from low-priv auth to RCE (T1068).

Confidence: HIGH · MITRE ATT&CK Enterprise v19.0

NVD Description

Census CSWeb 8.0.1 allows arbitrary file upload. A remote, authenticated attacker could upload a malicious file, possibly leading to remote code execution. Fixed in 8.1.0 alpha.

Deeper analysisAI

CVE-2025-60947 is an arbitrary file upload vulnerability affecting Census CSWeb version 8.0.1. Published on 2026-03-23, it is classified under CWE-434 (Unrestricted Upload of File with Dangerous Type) with a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). The flaw enables a remote, authenticated attacker to upload a malicious file, potentially resulting in remote code execution.

A remote attacker with low-privilege authenticated access can exploit this vulnerability over the network with low complexity and no user interaction required. Successful exploitation grants high-impact access to confidentiality, integrity, and availability, allowing the attacker to execute arbitrary code on the server by uploading and triggering a malicious file.

Mitigation is available in Census CSWeb 8.1.0 alpha, as indicated by the patching commit at https://github.com/csprousers/csweb/commit/eba0b59a243390a1a4f9524cce6dbc0314bf0d91. Additional resources include a CISA advisory at https://raw.githubusercontent.com/cisagov/CSAF/develop/csaf_files/IT/white/2026/va-26-082-01.json, the official CVE record at https://www.cve.org/CVERecord?id=CVE-2025-60947, and an exploits repository at https://github.com/hx381/cspro-exploits. Security practitioners should upgrade to the fixed version and review access controls for file upload functionalities.
