AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
A memory leak vulnerability in Huawei NIP6800, Secospace USG6600, and USG9500 allows a high-privilege attacker to cause service abnormal.
Vulnerability
A memory leak vulnerability exists in Huawei NIP6800, Secospace USG6600, and USG9500 products. The affected versions include NIP6800 V500R001C60SPC500, Secospace USG6600 V500R001C30SPC200, V500R001C30SPC600, V500R001C60SPC500, and USG9500 V500R001C30SPC200 [1]. The vulnerability is triggered when an attacker with high privileges continuously performs specific operations, leading to memory exhaustion.
Exploitation
An attacker must have high privileges on the affected device. By repeatedly executing specific operations (not further detailed in the advisory), the attacker can cause the system to leak memory over time. No user interaction or network position beyond authenticated access is required.
Impact
Successful exploitation results in memory exhaustion, leading to service abnormal (denial of service). The attacker can degrade or disrupt the normal operation of the device, affecting availability.
Mitigation
Huawei has released software updates to fix this vulnerability. The resolved versions are: NIP6800 upgrade to V500R005C00SPC200, Secospace USG6600 upgrade to V500R005C00SPC200, and USG9500 upgrade to V500R005C00SPC200 [1]. No workarounds are mentioned; users should apply the patches as soon as possible.
