DLP UserCheck Web Portal Input Handling Issue

Publication date: 2026-05-26

Last updated on: 2026-05-26

Assigner: Check Point Software Technologies Ltd.

Description
When the DLP is active, the UserCheck Web Portal contains an input-handling issue in the UserChoice flow. Under specific conditions, an attacker who can access the UserCheck Ask page could attempt to manipulate the Security Gateway's stored DLP/UserCheck incident information. This could lead to disruptions such as loss of stored incident entries, incorrect handling of pending approvals, or resource impact if the issue is abused repeatedly. Exposure is reduced if the UserCheck Portal is not accessible from untrusted networks.

CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

This vulnerability occurs in the UserCheck Web Portal when Data Loss Prevention (DLP) is active. It involves an input-handling issue in the UserChoice flow that allows an attacker who can access the UserCheck Ask page to manipulate the Security Gateway's stored DLP/UserCheck incident information.

Under specific conditions, this manipulation can lead to disruptions such as loss of stored incident entries, incorrect handling of pending approvals, or resource impact if the issue is exploited repeatedly.

Impact Analysis

The vulnerability can impact you by causing loss of stored incident data, which may affect your ability to track and respond to security incidents properly.

It can also lead to incorrect handling of pending approvals, potentially disrupting normal security workflows.

Repeated exploitation of this issue could cause resource impact, possibly degrading system performance or availability.

Mitigation Strategies

Exposure to this vulnerability is reduced if the UserCheck Portal is not accessible from untrusted networks.

Compliance Impact

The vulnerability in the UserCheck Web Portal could lead to manipulation or loss of stored DLP/UserCheck incident information, which may impact the integrity and availability of security incident data.

Such disruptions could potentially affect compliance with standards and regulations like GDPR and HIPAA, which require proper handling, protection, and retention of security incident data to ensure data privacy and security.

However, the provided information does not explicitly state the direct impact on compliance with these regulations.
