Open ISES Tickets: TLS Certificate Verification Bypass in Login Process.

CVE advisorySeverity: HIGH (CVSS 8.2)

CVE-2026-48248

A flaw in Open ISES Tickets allows attackers to intercept sensitive data during login by bypassing security certificate checks. This impacts organizations using affected versions, risking exposure of API keys or session data. The realistic business risk involves potential data compromise during transit.

Halo Surface Signal score for CVE-2026-48248

The vulnerability exists in code responsible for outbound HTTPS requests during the login and authentication flow of a ticketing application. While this server-side logic is triggered by user authentication, it is not a direct public-facing interface itself, but rather an internal processing step that could be reached by an attacker if the application performs such requests to external services.

Horizon Alert

Summary of the vulnerability and why it matters

The Open ISES Tickets application has a vulnerability related to how it handles secure connections during the login process. This flaw could allow an attacker to intercept sensitive information transmitted during authentication. Such an interception could expose data such as API keys or session details.

  • Vulnerable login process
  • Disables security certificate checks
  • Potential data interception

Attack Path

How an attacker could exploit the issue

The vulnerability stems from a failure to verify TLS certificates during the login process. This allows a network-positioned attacker to impersonate legitimate endpoints. Such an attacker can then intercept and manipulate data exchanged between the application and remote services, potentially compromising sensitive information like API keys or session data.

  • Exposed to network attackers.
  • Attacker intercepts requests.
  • Sensitive data can be modified.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability involves how the Open ISES Tickets application handles secure connections during its login process. By disabling a crucial security check for digital certificates, the application could allow attackers on the network path to intercept or alter sensitive information exchanged between the server and other endpoints. This could expose API keys or session data during transit, posing a risk to the confidentiality of communications.

  • Likely attacker skill level: Moderate
  • Required access or conditions: Network access
  • Business risk or urgency: Moderate

Priority actions

Operational Fix

Recommended remediation, mitigation, and detection steps

This vulnerability impacts organizations using Open ISES Tickets prior to version 3.44.2. Attackers on the network path can present forged certificates to intercept, monitor, or modify data during the login and authentication process. This poses a risk to sensitive information like API keys or session data transmitted in transit.

  • Identify exposed assets.
  • Reduce exposure or isolate risk.
  • Fix, verify, and monitor.

Frequently asked questions

What is Open ISES Tickets and its primary function?

Open ISES Tickets is a software application designed for managing and processing tickets. Its main use is within contexts like customer support or issue tracking, where it facilitates user login and authentication to interact with the system.

How does CVE-2026-48248 affect Open ISES Tickets' security?

CVE-2026-48248, classified under CWE-295 (Improper Certificate Validation), weakens Open ISES Tickets by disabling TLS certificate verification during login. This prevents the software from confirming the identity of servers it connects to, creating a security risk.

What is the attack path for CVE-2026-48248 in Open ISES Tickets?

An attacker on the network path can exploit this vulnerability by presenting a forged certificate. This allows them to intercept, monitor, or alter requests and responses during the login process, potentially capturing sensitive data in transit.

What is the relevance of this TLS verification bypass to security?

The bypass of TLS certificate verification in Open ISES Tickets is relevant because it exposes sensitive data like API keys or session information to interception and modification by network-positioned attackers during authentication.

What steps should be taken to respond to this vulnerability?

To address this, organizations should identify affected Open ISES Tickets assets, reduce exposure, and apply the fix by updating to version 3.44.2 or later. Continuous monitoring after the fix is also recommended.
