Security readout for executives and security teams
Plain-English summary
Some Juniper SRX firewalls can expose user credentials when HTTP or HTTPS pass-through authentication is enabled. The issue is configuration-dependent and affects older Junos OS releases. The main business risk is credential disclosure, not system takeover or service outage.
Executive priority
Treat as a moderate-priority firewall hygiene issue. Prioritize internet-edge or sensitive network SRX devices using HTTP/HTTPS pass-through authentication, because exposed credentials can enable follow-on account misuse.
Technical view
CVE-2018-0025 affects Junos OS on SRX Series when HTTP/HTTPS firewall pass-through user authentication is configured. Credentials sent in an initial session may be captured in later HTTP/HTTPS requests by a man-in-the-middle attacker or a subverted authentic server. FTP and Telnet pass-through authentication are listed as unaffected.
Likely exposure
Exposure is limited to Juniper SRX Series devices running affected 12.1X46, 12.3X48, or 15.1X49 releases with HTTP or HTTPS pass-through authentication enabled.
Exploitation context
The source bundle does not show CISA KEV listing or active exploitation. Exploitation requires user interaction and a position to observe or influence follow-on HTTP/HTTPS requests, such as man-in-the-middle access or control of a trusted server.
Researcher notes
CVSS 3.0 is 6.1 with high confidentiality impact, no integrity or availability impact, high attack complexity, and required user interaction. The record maps to CWE-300 and CWE-319. Evidence is strongest for affected versions and configuration conditions; exploit activity is not established.
Mitigation direction
- Upgrade 12.1X46 to 12.1X46-D67 or later.
- Upgrade 12.3X48 to 12.3X48-D25 or later.
- Upgrade 15.1X49 to 15.1X49-D35 or later.
- Disable HTTP/HTTPS pass-through authentication if it is not operationally required.
- Review Juniper advisory JSA10858 for vendor-specific guidance.
Validation and detection
- Inventory SRX Series devices and record exact Junos OS versions.
- Identify configurations using HTTP or HTTPS pass-through user authentication.
- Confirm FTP and Telnet pass-through authentication are not treated as affected paths.
- Verify upgraded devices meet or exceed the fixed release thresholds.
- Review network paths where authenticated HTTP/HTTPS traffic could be intercepted.
