CVE-2026-106035: Ivanti Xtraction Cloud Sync Log Exposure

CVE-2026-106035 Overview

CVE-2026-106035 is an information disclosure vulnerability in Ivanti Xtraction Cloud Sync affecting versions prior to 2026.4. The flaw stems from improper handling of sensitive data in application log files [CWE-532]. A remote authenticated attacker with local access to the system can read application logs to obtain partial SQL database passwords. The exposure undermines the confidentiality of database credentials used by the Xtraction Cloud Sync component.

Critical Impact
Authenticated attackers with access to log files can recover partial SQL database passwords, which may enable follow-on attacks against the backend database or facilitate credential-based lateral movement.

Affected Products

Ivanti Xtraction Cloud Sync versions prior to 2026.4
Deployments where application logs are accessible to authenticated users
Environments relying on SQL authentication for the Xtraction database backend

Technical Details for CVE-2026-106035

Vulnerability Analysis

The vulnerability is categorized as Insertion of Sensitive Information into Log File [CWE-532]. Ivanti Xtraction Cloud Sync writes partial SQL database password material into application log files during normal operation. Any authenticated user who can access those log files on the host can read the exposed fragments.

The advisory indicates only partial password disclosure, but partial credential leakage still reduces the search space for brute-force or dictionary attacks. If the backend database is reachable from the attacker, recovered credentials can be used to query or modify records directly. The flaw requires local access and low-privileged authentication, which limits remote exploitation but does not eliminate insider or post-compromise risk.

Root Cause

The root cause is insufficient sanitization of credential material prior to log emission. Application code paths that handle database connection setup or error reporting write password fragments into log entries without masking or redaction. Defensive logging practices require that secrets be filtered or replaced with placeholder tokens before serialization.

Attack Vector

Exploitation requires local access to the Xtraction Cloud Sync host and valid low-privileged credentials. The attacker reads application log files from disk and parses them for leaked SQL password fragments. No network access to the Xtraction service itself is required beyond the initial authentication. The attack does not alter system state and leaves minimal forensic indicators beyond log file read events.

See the Ivanti Security Advisory for vendor-provided technical details.

Detection Methods for CVE-2026-106035

Indicators of Compromise

Unexpected read access to Xtraction Cloud Sync application log directories by non-administrative accounts
Log entries containing fragments of database connection strings or password material
Authentication attempts against the backend SQL database from hosts not previously observed as database clients

Detection Strategies

Audit log file access events on hosts running Ivanti Xtraction Cloud Sync, focusing on interactive user sessions
Scan existing log archives for regex patterns matching partial credential strings and rotate any exposed secrets
Correlate log read activity with subsequent authentication attempts against the SQL backend

Monitoring Recommendations

Enable file integrity and access monitoring on the Xtraction application log directory
Forward application logs to a centralized SIEM for retention and anomaly detection
Alert on database authentication failures that follow log file access by the same user context

How to Mitigate CVE-2026-106035

Immediate Actions Required

Upgrade Ivanti Xtraction Cloud Sync to version 2026.4 or later
Rotate SQL database credentials used by Xtraction Cloud Sync after upgrading
Restrict file system permissions on application log directories to administrators only
Review historical log archives for exposed credential fragments and purge where appropriate

Patch Information

Ivanti has released a fixed build in Xtraction Cloud Sync version 2026.4. Refer to the Ivanti Security Advisory for the complete list of addressed CVEs and upgrade instructions.

Workarounds

Limit local and remote interactive access to the Xtraction Cloud Sync host to trusted administrators
Apply strict access control lists on log directories to block read access by low-privileged accounts
Configure log rotation and secure archival to minimize the window of exposure for any sensitive entries

bash

# Example: restrict log directory access on Windows (PowerShell)
icacls "C:\ProgramData\Ivanti\Xtraction\Logs" /inheritance:r
icacls "C:\ProgramData\Ivanti\Xtraction\Logs" /grant:r "Administrators:(OI)(CI)F" "SYSTEM:(OI)(CI)F"
