CVE-2025-49536: Adobe ColdFusion Auth Bypass Vulnerability

CVE-2025-49536 Overview

CVE-2025-49536 is an Incorrect Authorization vulnerability [CWE-863] affecting Adobe ColdFusion versions 2025.2, 2023.14, 2021.20, and earlier. A low-privileged attacker on an adjacent network can bypass security controls and gain unauthorized access to protected functionality. Exploitation requires no user interaction, though the vulnerable component is restricted to internal IP addresses.

Adobe published the advisory as APSB25-69 on July 8, 2025. The flaw impacts confidentiality and integrity of ColdFusion application data but does not affect availability.

Critical Impact
Authenticated adjacent-network attackers can bypass ColdFusion authorization controls to access restricted resources and modify protected data on affected servers.

Technical Details for CVE-2025-49536

Vulnerability Analysis

CVE-2025-49536 stems from an authorization logic flaw in ColdFusion's access control mechanism. The vulnerable component fails to correctly verify whether an authenticated user holds the privileges required to perform a requested action. As a result, a low-privileged account can invoke functionality reserved for higher-privilege roles.

The issue is classified under CWE-863: Incorrect Authorization. This category covers cases where an application performs an authorization check but reaches an incorrect decision, granting access to resources or operations the caller should not reach.

The attack surface is scoped to adjacent networks, meaning the attacker must be positioned on the same logical network segment as the ColdFusion server. Adobe notes the vulnerable component is restricted to internal IP addresses, reducing exposure for properly segmented deployments but leaving internal attackers and pivoting adversaries with a viable path.

Root Cause

The root cause is missing or incomplete authorization enforcement on a ColdFusion component that trusts request context without validating the caller's privilege level. When a low-privileged session sends a crafted request, the component processes it as if the caller were authorized.

Attack Vector

An attacker must first authenticate with low-level credentials to a ColdFusion instance reachable on the internal network. The attacker then issues requests to the vulnerable component, bypassing role checks to read or modify restricted data. No user interaction is required, and no additional exploitation primitives such as memory corruption are needed.

Adobe has not published proof-of-concept code, and no public exploit is currently listed in Exploit-DB. Technical details beyond the vendor advisory are limited. See the Adobe ColdFusion Security Advisory APSB25-69 for vendor guidance.

Detection Methods for CVE-2025-49536

Indicators of Compromise

Authenticated ColdFusion sessions from low-privileged accounts accessing administrative endpoints or components outside their normal role scope.
Unusual internal HTTP requests to ColdFusion Administrator or CFIDE paths originating from user accounts that do not typically interact with those endpoints.
Modifications to ColdFusion configuration, datasources, or scheduled tasks made by non-administrator accounts.

Detection Strategies

Audit ColdFusion access logs for privilege mismatches: successful requests to restricted components by accounts whose role does not include those permissions.
Correlate authentication events with subsequent authorization-sensitive actions to identify sessions that escalate scope after login.
Deploy signatures for anomalous request patterns targeting /CFIDE/administrator/ and adjacent management paths from internal user segments.

Monitoring Recommendations

Enable verbose authorization logging on ColdFusion and forward events to a centralized SIEM for role-based analysis.
Alert on any successful administrative action performed by an account not in the administrator role group.
Monitor east-west traffic to ColdFusion servers and baseline expected clients so unexpected internal peers trigger investigation.

How to Mitigate CVE-2025-49536

Immediate Actions Required

Apply the security updates referenced in Adobe bulletin APSB25-69 to upgrade ColdFusion 2025, 2023, and 2021 installations to fixed releases.
Restrict network access to ColdFusion servers so only trusted internal segments can reach the vulnerable component.
Review and reduce the number of low-privileged accounts with authenticated access to ColdFusion, and rotate credentials for accounts under suspicion.

Patch Information

Adobe released fixed builds addressing CVE-2025-49536 on July 8, 2025. Administrators should install the updates documented in the Adobe ColdFusion Security Advisory APSB25-69. Upgrading past ColdFusion 2025.2, 2023.14, and 2021.20 remediates the incorrect authorization flaw.

Workarounds

Enforce network segmentation and firewall rules that limit ColdFusion Administrator and internal component access to a dedicated management VLAN.
Apply the ColdFusion Lockdown Guide recommendations to reduce the accessible attack surface for authenticated users.
Audit role assignments in ColdFusion and remove unnecessary privileges from application service accounts until the patch is deployed.

bash

# Example: restrict ColdFusion Administrator access to a management subnet using iptables
iptables -A INPUT -p tcp --dport 8500 -s 10.10.50.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 8500 -j DROP
