A vulnerability was found in Huawei RP200, TE30, TE40, TE50 and TE60 (Unified Communication Software) and classified as critical. This issue affects an unknown code block of the component SS7 Packet Handler. The manipulation with an unknown input leads to a out-of-bounds vulnerability. Using CWE to declare the problem leads to CWE-125. The product reads data past the end, or before the beginning, of the intended buffer. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

RP200 V500R002C00, V600R006C00; TE30 V100R001C10, V500R002C00, V600R006C00; TE40 V500R002C00, V600R006C00; TE50 V500R002C00, V600R006C00; TE60 V100R001C10, V500R002C00, V600R006C00 have an out-of-bounds read vulnerabilities in some Huawei products. Due to insufficient input validation, a remote attacker could exploit these vulnerabilities by sending specially crafted SS7 related packets to the target devices. Successful exploit will cause out-of-bounds read and possibly crash the system.
