CVE-2026-63082 in Perfect Support Ticketing & Document Management System
Summary
by MITRE • 07/16/2026
Perfect Support Ticketing & Document Management System through 1.7 contains a broken access control vulnerability that allows authenticated attackers with Agent-level privileges to manipulate the Support Agent assignment field of tickets by bypassing intended authorization checks. Attackers can add or remove any user, including Superadmin accounts, from the Support Agent field of any ticket to which they are assigned, circumventing role-based access controls.

This vulnerability represents a critical broken access control flaw that undermines the fundamental security model of the support ticketing system. The issue manifests when authenticated users with Agent-level privileges exploit a design weakness in the authorization mechanism governing ticket assignment fields. The system fails to properly validate whether an agent should have the authority to modify the Support Agent field of tickets, creating an unauthorized manipulation vector that allows privilege escalation through indirect means. This flaw directly violates the principle of least privilege and demonstrates poor implementation of access control policies.
The technical execution of this vulnerability occurs through a direct bypass of intended authorization checks within the system's backend validation logic. When an authenticated agent attempts to modify the Support Agent field of any ticket they are assigned to, the system does not properly verify whether the agent possesses sufficient privileges to make such modifications. This allows attackers to inject malicious payloads or manipulate data structures that control agent assignments, effectively granting them the ability to add or remove users from tickets regardless of their actual role permissions. The vulnerability specifically impacts the assignment field validation mechanism and demonstrates a failure in proper input sanitization and access verification.
The operational impact of this vulnerability extends beyond simple privilege escalation as it enables attackers to manipulate critical support workflows and potentially gain unauthorized access to sensitive information. By removing Superadmin accounts from ticket assignments, attackers can effectively disrupt support operations and create blind spots in the system's monitoring capabilities. The ability to add unauthorized users to tickets could allow for persistent backdoor access or enable attackers to impersonate legitimate administrators within the support environment. This vulnerability directly affects the integrity of the support ticketing workflow and undermines the trust model that should exist between different user roles.
Organizations implementing this system face significant security risks including potential data breaches, unauthorized access to sensitive support tickets, and disruption of critical business operations. The vulnerability creates an attack surface that allows for both active exploitation and potential long-term persistence within the support infrastructure. Security teams must recognize this as a high-severity issue requiring immediate attention, as it enables attackers to effectively circumvent role-based access controls that are fundamental to maintaining system integrity and protecting sensitive data.
Mitigation strategies should focus on implementing proper authorization checks at multiple levels including input validation, session management, and role-based access control enforcement. The system requires comprehensive revalidation of all user actions when modifying ticket assignment fields, with explicit permission checks for each modification attempt. Organizations should implement principle of least privilege controls that prevent agents from making modifications to fields they do not legitimately require access to. Regular security testing including penetration testing and code reviews should be conducted to identify similar authorization bypass vulnerabilities. This vulnerability aligns with CWE-285 which addresses improper authorization issues, and represents a clear violation of ATT&CK technique T1078 for Valid Accounts and T1484 for Domain Policy Modification.
The remediation approach must include complete overhaul of the access control validation logic specifically targeting ticket assignment modifications. All user actions involving agent field changes should require explicit permission verification against the system's role hierarchy before any modifications are accepted. Implementing proper audit logging of all agent assignment changes will help detect unauthorized activities and provide forensic evidence for security investigations. Additionally, regular updates to the authentication and authorization frameworks should be implemented to prevent similar issues in future releases and maintain compliance with industry standards such as those outlined in ISO 27001 and NIST cybersecurity frameworks. The solution must ensure that no user can manipulate ticket assignments without proper authorization and that all modifications are traceable through comprehensive logging mechanisms.
