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.

There is an integer overflow vulnerability in LDAP client of some Huawei products. Due to insufficient input validation, a remote attacker could exploit this vulnerability by sending malformed packets to the target devices. Successful exploit could cause the affected system crash.

GE PACSystems RX3i CPE100/115: All versions prior to R9.85,CPE302/305/310/330/400/410: All versions prior to R9.90,CRU/320 All versions(End of Life) may allow an attacker sending specially manipulated packets to cause the module state to change to halt-mode, resulting in a denial-of-service condition. An operator must reboot the CPU module after removing battery or energy pack to recover from halt-mode.

An unauthenticated, remote attacker has to control the peer device and send specially crafted message to the affected products. Due to insufficient input validation, successful exploit may cause some services abnormal.

Huawei DP300 V500R002C00; RP200 V500R002C00; V600R006C00; TE30 V100R001C10; V500R002C00; V600R006C00; TE40 V500R002C00; V600R006C00; TE50 V500R002C00; V600R006C00; TE60 V100R001C10; V500R002C00; V600R006C00 have an out-of-bounds read vulnerability. An unauthenticated, remote attacker has to control the peer device and craft the Signalling Connection Control Part (SCCP) messages to the target devices. Due to insufficient input validation of some values in the messages, successful exploit will cause out-of-bounds read and some services abnormal.

An unauthenticated, remote attacker may send specially crafted SCCP messages to the affected products. Due to the improper validation of the messages, it will cause numeric errors when handling the messages. Successful exploit will cause some services abnormal.

In GE PACSystems RX3i CPE305/310 version 9.20 and prior, RX3i CPE330 version 9.21 and prior, RX3i CPE 400 version 9.30 and prior, PACSystems RSTi-EP CPE 100 all versions, and PACSystems CPU320/CRU320 RXi all versions, the device does not properly validate input, which could allow a remote attacker to send specially crafted packets causing the device to become unavailable.

Huawei DP300 V500R002C00, RP200 V600R006C00, TE30 V100R001C10, V500R002C00, V600R006C00, TE40 V500R002C00, V600R006C00, TE50 V500R002C00, V600R006C00, TE60 V100R001C10, V500R002C00, V600R006C00 have an invalid memory access vulnerability. An unauthenticated attacker has to find a way to send malformed SCCP messages to the affected products. Due to insufficient input validation of some values in the messages, successful exploit may cause buffer error and some service abnormal.
