CVE-2025-1723: ManageEngine ADSelfService Plus Auth Bypass

CVE-2025-1723 Overview

CVE-2025-1723 is a session mishandling vulnerability affecting Zohocorp ManageEngine ADSelfService Plus versions 6510 and below. This authentication bypass vulnerability (CWE-287) allows valid account holders within the setup to exploit improper session management, potentially leading to account takeover. The vulnerability requires low privileges but can be exploited remotely over the network without user interaction, making it a significant threat to organizations relying on ADSelfService Plus for self-service password management and single sign-on capabilities.

Critical Impact

Authenticated attackers can exploit session mishandling to take over other user accounts, potentially gaining access to privileged credentials and compromising Active Directory identity management infrastructure.

Affected Products

• Zohocorp ManageEngine ADSelfService Plus version 6510 and all prior builds
• Zohocorp ManageEngine ADSelfService Plus versions 6500 through 6510
• All ADSelfService Plus 6.5.x deployments with build numbers at or below 6510

Technical Details for CVE-2025-1723

Vulnerability Analysis

This vulnerability stems from improper authentication handling (CWE-287) in the session management component of ManageEngine ADSelfService Plus. The flaw allows authenticated users with low-level privileges to exploit session mishandling mechanisms to gain unauthorized access to other user accounts. The attack can be executed remotely over the network and does not require any user interaction from the victim.

The vulnerability impacts both confidentiality and integrity of the affected system, as attackers can potentially access sensitive user credentials and modify account settings. Since ADSelfService Plus is commonly deployed as a centralized password management and single sign-on solution integrated with Active Directory, successful exploitation could provide attackers with a foothold for lateral movement within enterprise environments.

Root Cause

The root cause of CVE-2025-1723 lies in improper session handling within the ADSelfService Plus application. The session management implementation fails to properly validate and isolate user sessions, allowing authenticated users to manipulate session tokens or identifiers to access other accounts. This improper authentication vulnerability enables session confusion or session token prediction that bypasses the intended access control mechanisms.

Attack Vector

The attack vector for CVE-2025-1723 is network-based, requiring an authenticated user with a valid account in the ADSelfService Plus setup. The attacker must first authenticate to the application with low-level privileges. From this authenticated position, they can exploit the session mishandling flaw to hijack or access sessions belonging to other users, including potentially privileged accounts.

The exploitation does not require social engineering or user interaction from the target victim. The low attack complexity combined with the potential for account takeover makes this vulnerability particularly dangerous in environments where ADSelfService Plus manages credentials for high-privilege accounts.

Detection Methods for CVE-2025-1723

Indicators of Compromise

• Unusual session activity patterns where a single user account accesses multiple distinct session tokens in rapid succession
• Authentication logs showing session token reuse or manipulation attempts
• Anomalous account modifications or password reset activities attributed to unexpected user accounts
• Multiple concurrent sessions from different IP addresses for the same user identity

Detection Strategies

• Monitor ADSelfService Plus audit logs for session-related anomalies and unexpected privilege escalation events
• Implement SIEM correlation rules to detect multiple session ID assignments to a single authenticated user within a short timeframe
• Deploy behavioral analytics to identify users accessing accounts or performing actions inconsistent with their normal activity patterns
• Review web application firewall logs for suspicious requests targeting session management endpoints

Monitoring Recommendations

• Enable verbose logging for authentication and session management events in ADSelfService Plus
• Configure alerts for account takeover indicators such as password changes followed immediately by new authentication from different locations
• Implement real-time monitoring of Active Directory audit events that may indicate compromised credentials being used
• Establish baseline user behavior profiles to detect deviations indicative of account compromise

How to Mitigate CVE-2025-1723

Immediate Actions Required

• Upgrade ManageEngine ADSelfService Plus to a version above 6510 immediately
• Review authentication and session logs for any indicators of exploitation prior to patching
• Audit user accounts for unauthorized modifications or suspicious activity
• Implement network segmentation to limit exposure of ADSelfService Plus to trusted networks only

Patch Information

Zohocorp has released a security update addressing CVE-2025-1723. Organizations should upgrade to a version higher than build 6510 to remediate this vulnerability. Detailed patching instructions and the updated software are available from the ManageEngine Security Advisory.

Workarounds

• Restrict network access to the ADSelfService Plus web interface to trusted IP ranges only
• Implement additional authentication factors (MFA) for all ADSelfService Plus users to add a layer of protection
• Temporarily disable non-essential user accounts until the patch can be applied
• Monitor session management endpoints with web application firewall rules to detect exploitation attempts

# Example: Restrict access to ADSelfService Plus via firewall
# Allow only trusted management networks
iptables -A INPUT -p tcp --dport 443 -s 10.0.0.0/8 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
