CVE-2019-19417

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.

7.5 3.1 HIGH
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
