Horizon Alert
Summary of the vulnerability and why it matters
Open ISES Tickets is vulnerable due to improper handling of TLS certificate verification for outbound HTTPS requests. This weakness allows an attacker on the network path to present a forged certificate. Such an interception could lead to the exposure of sensitive data transmitted in transit.
- Outbound HTTPS request functions
- Disabled TLS certificate verification
- Sensitive data exposure
Attack Path
How an attacker could exploit the issue
This vulnerability impacts organizations using Open ISES Tickets version 3.44.2 and earlier. The software's TLS certificate verification is disabled for outbound HTTPS requests. This allows an attacker on the network path to intercept or modify sensitive data transmitted between the server and remote endpoints. The potential for data exposure includes API keys and session information.
- Outbound HTTPS requests lack verification.
- Attacker intercepts network traffic.
- Forged certificates enable data manipulation.
Live Threat
Current exploitation, exposure, and threat context
The Open ISES Tickets software has a vulnerability that could allow an attacker to intercept or modify data sent over HTTPS connections. This occurs because the software improperly disables security checks for TLS certificates. An attacker positioned on the network between the affected server and the intended recipient could exploit this by presenting a fake certificate. This could expose sensitive information, such as API keys or session data, that is transmitted during these communications.
- Attackers need network access.
- Exploitation requires man-in-the-middle.
- Data interception or modification is possible.
Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
This vulnerability allows an attacker on the network path to intercept or modify outbound HTTPS requests by presenting a forged certificate. This could expose sensitive data, such as API keys, if the requests contain such information. The issue arises from the system disabling TLS certificate verification for general outbound HTTPS requests.
- Find systems making outbound HTTPS requests.
- Reduce exposure by restricting network access.
- Apply vendor fix, verify, and monitor.
