CVE-2025-25181: Advantive Veracore SQLi Vulnerability

CVE-2025-25181 Overview

CVE-2025-25181 is a SQL injection vulnerability [CWE-89] in timeoutWarning.asp within Advantive VeraCore through version 2025.1.0. Remote unauthenticated attackers execute arbitrary SQL commands by manipulating the PmSess1 parameter. The flaw enables database content disclosure without requiring authentication or user interaction. CISA added CVE-2025-25181 to the Known Exploited Vulnerabilities (KEV) catalog after observing active exploitation by the XE Group, a threat actor previously associated with credit card skimming campaigns. The Exploit Prediction Scoring System (EPSS) score reaches 72.054% at the 98.773 percentile, indicating a high probability of continued exploitation activity.

Critical Impact
Unauthenticated remote attackers can extract sensitive database content from VeraCore deployments through the vulnerable PmSess1 parameter, with confirmed in-the-wild exploitation by the XE Group.

Affected Products

Advantive VeraCore (all versions through 2025.1.0)
VeraCore deployments exposing timeoutWarning.asp to the network
Order management and warehouse fulfillment environments running affected VeraCore builds

Technical Details for CVE-2025-25181

Vulnerability Analysis

The vulnerability resides in the timeoutWarning.asp script of Advantive VeraCore, a supply chain and order management platform. The script accepts the PmSess1 parameter without proper sanitization or parameterized query enforcement. Attackers inject SQL syntax through this parameter, causing the backend database to execute attacker-controlled statements.

Research published by Intezer and Solis Security attributes exploitation to the XE Group. The actor chained CVE-2025-25181 with other zero-day flaws to maintain persistent access in victim environments. Reporting indicates the attackers used the SQL injection to enumerate database content and support follow-on intrusion activity, including webshell deployment in compromised VeraCore instances.

Root Cause

The root cause is improper neutralization of special elements used in an SQL command [CWE-89]. The timeoutWarning.asp handler concatenates user-supplied input from the PmSess1 parameter directly into SQL statements. The application does not apply input validation, prepared statements, or stored procedures, allowing attacker-controlled tokens to alter query structure.

Attack Vector

The attack vector is network-based and requires no authentication or user interaction. An attacker issues an HTTP request to the timeoutWarning.asp endpoint with a crafted PmSess1 value. The injected SQL executes within the application's database context, returning data or modifying server-side state depending on database permissions. Because the endpoint is reachable pre-authentication, exposed VeraCore instances on the internet face direct exploitation. Refer to the Intezer Blog Research and Solis Security XE Group Analysis for observed exploitation details.

Detection Methods for CVE-2025-25181

Indicators of Compromise

HTTP requests to timeoutWarning.asp containing SQL metacharacters such as single quotes, UNION, SELECT, --, or ; within the PmSess1 parameter
Unexpected ASPXSPY, reGeorg, or other webshell artifacts deployed on VeraCore web servers following suspicious requests
Outbound connections from VeraCore application servers to infrastructure associated with the XE Group as documented by Intezer and Solis Security
Database audit log entries showing unusual query patterns originating from the VeraCore application account

Detection Strategies

Inspect IIS and web application logs for requests to timeoutWarning.asp with anomalous PmSess1 parameter lengths or non-session-token content
Deploy WAF signatures targeting SQL injection patterns specifically scoped to the VeraCore URI paths
Correlate web request anomalies with downstream SQL Server query telemetry to identify injection success

Monitoring Recommendations

Forward IIS logs, SQL Server audit logs, and EDR telemetry from VeraCore hosts to a central analytics platform for correlation
Alert on creation of new .asp, .aspx, or executable files in VeraCore web directories outside of vendor patch windows
Monitor for new local accounts, scheduled tasks, or services on VeraCore servers consistent with post-exploitation persistence

How to Mitigate CVE-2025-25181

Immediate Actions Required

Identify all internet-exposed VeraCore instances and restrict access to timeoutWarning.asp via network controls until patches are applied
Contact Advantive support through the Advantive Knowledge Base to obtain the remediated build and apply it across all VeraCore environments
Hunt for prior compromise by reviewing web logs and host artifacts using the indicators published in the Intezer Blog Research
Rotate database credentials, session secrets, and any administrative passwords stored within affected VeraCore deployments

Patch Information

Advantive has published remediation guidance through its customer knowledge base. Administrators should reference the Advantive Knowledge Base and the CISA KEV entry for CVE-2025-25181 for upgrade requirements and federal remediation deadlines.

Workarounds

Block external access to timeoutWarning.asp at the reverse proxy or WAF layer until patching is complete
Apply WAF rules that reject requests where the PmSess1 parameter contains SQL keywords or metacharacters
Enforce least-privilege permissions on the SQL Server account used by VeraCore to limit the impact of successful injection
Place VeraCore behind a VPN or IP allow-list to reduce exposure of the vulnerable endpoint

bash

# Example WAF rule snippet to block SQL metacharacters in PmSess1
SecRule ARGS:PmSess1 "@rx (?i)(union|select|insert|update|delete|--|;|/\*|\bor\b\s+1=1)" \
