Description: In Apache Traffic Control Traffic Ops prior to 6.1.0 or 5.1.6, an unprivileged user who can reach Traffic Ops over HTTPS can send a specially-crafted POST request to /user/login/oauth to scan a port of a server that Traffic Ops can reach.
Mitigation: 6.0.x user should upgrade to 6.1.0. 5.1.x users should upgrade to 5.1.6 or 6.1.0. Credit: Apache Traffic Control would like to thank walkerxiong of SecCoder Security Lab for reporting this issue.
