Summary

MAX PRESENCE V100R001C00, TP3106 V100R002C00, TP3206 V100R002C00 have an a memory leak vulnerability in H323 protocol. An attacker logs in to the system as a user and send crafted packets to the affected products. Due to insufficient verification of the packets, successful exploit could cause a memory leak and eventual denial of service (DoS) condition.

Common Attack Pattern Enumeration and Classification (CAPEC)

  • HTTP DoS
    An attacker performs flooding at the HTTP level to bring down only a particular web application rather than anything listening on a TCP/IP connection. This denial of service attack requires substantially fewer packets to be sent which makes DoS harder to detect. This is an equivalent of SYN flood in HTTP. The idea is to keep the HTTP session alive indefinitely and then repeat that hundreds of times. This attack targets resource depletion weaknesses in web server software. The web server will wait to attacker's responses on the initiated HTTP sessions while the connection threads are being exhausted.
