- Severity: CVSS 7.4 (High), CNA
- Vector: CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:H
- Known exploited (CISA KEV): no
- Published: 2017-10-13 · Updated: 2024-09-16

## Affected

- Juniper Networks Junos OS: 12.1X46 prior to 12.3X46-D71, 12.3X48 prior to 12.3X48-D55, 15.1X49 prior to 15.1X49-D110

## Description

Juniper Networks Junos OS on SRX series devices do not verify the HTTPS server certificate before downloading anti-virus updates. This may allow a man-in-the-middle attacker to inject bogus signatures to cause service disruptions or make the device not detect certain types of attacks. Affected Junos OS releases are: 12.1X46 prior to 12.1X46-D71; 12.3X48 prior to 12.3X48-D55; 15.1X49 prior to 15.1X49-D110;
