The SIP module of some Huawei products have a denial of service (DoS) vulnerability. A remote attacker could exploit these three vulnerabilities by sending the specially crafted messages to the affected device. Due to the insufficient verification of the packets, successful exploit could allow the attacker to cause buffer overflow and dead loop, leading to DoS condition. Affected products can be found in https://www.huawei.com/en/psirt/security-advisories/huawei-sa-20200115-01-sip-en.

Multiple heap-based buffer overflows in the eSap software platform in Huawei Campus S9300, S7700, S9700, S5300, S5700, S6300, and S6700 series switches; AR150, AR160, AR200, AR1200, AR2200, AR3200, AR530, NetEngine16EX, SRG1300, SRG2300, and SRG3300 series routers; and WLAN AC6005, AC6605, and ACU2 access controllers allow remote attackers to cause a denial of service (device restart) via a crafted length field in a packet.

Huawei S7700, S9700, S9300 before V200R07C00SPC500, and AR200, AR1200, AR2200, AR3200 before V200R005C20SPC200 allows attackers with physical access to the CF card to obtain sensitive information.
