Medium CSRF

CVE-2025-55043 — Cross-Site Request Forgery (CSRF) in Murasoftware Mura Cms

MuraCMS through 10.1.10 contains a CSRF vulnerability in the bundle creation functionality (csettings.cfc createBundle method) that allows unauthenticated attackers to force administrators to create and save site bundles containing sensitive data to publicly accessible directories. This vulnerability enables complete data exfiltration including user accounts, password hashes, form submissions, email lists, plugins, and site content without administrator knowledge. This CSRF vulnerability enables complete data exfiltration from MuraCMS installations without requiring authentication. Attackers can force administrators to unknowingly create site bundles containing sensitive data, which are saved to publicly accessible web directories. The attack executes silently, leaving administrators unaware that confidential information has been compromised and is available for unauthorized download.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

EPSS 0.2% (30-day exploitation probability)+1
Technical severity (medium)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (Murasoftware Mura Cms).
The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
No fix documented in the sources: reduce exposure and monitor the vendor advisory.
Exploitation requires user interaction: tighten email/web filtering and warn affected users.
Search available logs for exploit probes matching the vulnerability class (csrf), errors and authentication anomalies.
