CVE-2026-11840 Overview
CVE-2026-11840 is an authenticated SQL injection vulnerability [CWE-89] affecting Zohocorp ManageEngine Password Manager Pro versions before 13232 and ManageEngine PAM360 versions before 8552. An authenticated attacker with low-level privileges can inject arbitrary SQL statements through the affected application interfaces. Successful exploitation grants full read, write, and availability impact against the backing database. Because these products store enterprise privileged credentials, compromise of the database directly exposes sensitive secrets used across the target environment.
Critical Impact
Authenticated attackers can execute arbitrary SQL statements against privileged credential vaults, exposing stored passwords, keys, and session data.
Affected Products
- Zohocorp ManageEngine Password Manager Pro versions before 13232
- Zohocorp ManageEngine PAM360 versions before 8552
- Deployments exposing the web management console to authenticated users

Technical Details for CVE-2026-11840
Vulnerability Analysis
The vulnerability is classified as SQL Injection [CWE-89]. It requires network access to the application and a valid authenticated session with low privileges. No user interaction is required for exploitation. The scope remains unchanged, but confidentiality, integrity, and availability of the database are each fully impacted.
Both Password Manager Pro and PAM360 are privileged access management platforms that store credentials, SSH keys, certificates, and session recordings. Database-level compromise translates directly to disclosure or manipulation of secrets governing downstream systems. Attackers who obtain vaulted credentials can pivot into upstream infrastructure that these platforms are designed to protect.
Root Cause
The root cause is insufficient validation or parameterization of user-supplied input passed into SQL queries executed by the application. When attacker-controlled data reaches the query engine without proper separation of code from data, injected clauses alter the query semantics. Zohocorp has addressed the flaw in Password Manager Pro build 13232 and PAM360 build 8552.
Attack Vector
Exploitation requires network reachability to the ManageEngine application and valid authenticated credentials. An attacker submits crafted parameter values to a vulnerable endpoint. The application concatenates those values into a SQL statement, allowing the attacker to extract data with UNION selects, modify records, or invoke database functions that impact availability. Detailed indicator information is available in the ManageEngine Security Advisory CVE-2026-11840.
No public proof-of-concept exploit is currently available for this issue.
Detection Methods for CVE-2026-11840
Indicators of Compromise
- Web access logs containing SQL metacharacters such as single quotes, UNION SELECT, --, or hex-encoded payloads in request parameters directed at Password Manager Pro or PAM360 endpoints.
- Unexpected database errors, long-running queries, or SELECT statements referencing internal metadata tables originating from the application service account.
- Authenticated sessions performing anomalous parameter probing against multiple endpoints in short intervals.
Detection Strategies
- Deploy WAF or reverse-proxy rules that inspect requests to ManageEngine URIs for SQL injection signatures, including tautologies and stacked queries.
- Correlate authenticated user activity with database query patterns to identify sessions issuing atypical query shapes or volumes.
- Alert on outbound data volumes from Password Manager Pro or PAM360 hosts that deviate from established baselines.
Monitoring Recommendations
- Enable verbose audit logging in Password Manager Pro and PAM360 and forward logs to a centralized SIEM for retention and correlation.
- Monitor database service account activity for schema enumeration, mass row reads, or writes to credential tables.
- Track privileged credential retrievals from the vault and flag bursts that do not align with normal operator workflows.
How to Mitigate CVE-2026-11840
Immediate Actions Required
- Upgrade Password Manager Pro to build 13232 or later, and PAM360 to build 8552 or later, following vendor upgrade guidance.
- Rotate credentials, API keys, and certificates stored in the vault if compromise is suspected or if the appliance was internet-exposed prior to patching.
- Restrict console and API access to trusted management networks and enforce multi-factor authentication for all users.
Patch Information
Zohocorp has released fixed builds for both affected products. Password Manager Pro build 13232 and PAM360 build 8552 remediate the SQL injection issue. Upgrade instructions and download links are published in the ManageEngine Security Advisory CVE-2026-11840.
Workarounds
- Limit accounts able to authenticate to the application while patching is scheduled, reducing the pool of potential attackers.
- Place the application behind a web application firewall configured with SQL injection rulesets tuned for the ManageEngine URI patterns.
- Segment the database host from general enterprise networks and restrict outbound connectivity from the application tier.
# Example: restrict Password Manager Pro console access with host-based firewall (Linux)
# Allow only the administrative jump host
iptables -A INPUT -p tcp --dport 7272 -s 10.10.5.25 -j ACCEPT
iptables -A INPUT -p tcp --dport 7272 -j DROP
