An unauthenticated, remote attacker could craft malformed packets and send the 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.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
A memory leak vulnerability in the H323 protocol of multiple Huawei products allows unauthenticated remote attackers to cause denial of service via crafted packets.
Vulnerability
A memory leak vulnerability exists in the H323 protocol implementation of multiple Huawei products. An unauthenticated, remote attacker can send specially crafted malformed packets to the affected product. Due to insufficient verification of the packets, the vulnerability can be exploited to cause a memory leak, eventually leading to a denial of service (DoS). Affected products include AR series, DP300, IPS Module, NGFW Module, NIP6300, NIP6600, NIP6800, NetEngine16EX, RSE6500, SRG series, SVN series, SeMG9811, Secospace USG series, and others running specific versions such as V200R006C10, V200R007C00, V200R008C20, V200R008C30, etc. [1]
Exploitation
An unauthenticated, remote attacker can exploit this vulnerability by sending crafted malformed packets to the affected product over the network. No authentication or user interaction is required. The attacker needs to craft packets that trigger the memory leak in the H323 protocol handling code. [1]
Impact
Successful exploitation can cause a memory leak, leading to gradual depletion of system memory resources. This results in a denial of service (DoS) condition, making the affected device unresponsive or causing process crashes. The impact is limited to availability; confidentiality and integrity are not directly affected. [1]
Mitigation
Huawei has released security updates to fix this vulnerability. Users should upgrade to the fixed versions as specified in the security advisory [1]. The advisory details the specific versions that address the issue. There are no known workarounds; applying the patch is the recommended mitigation. [1]
