CVE-2020-1827

Name of the Vulnerable Software and Affected Versions Huawei NIP6800 versions V500R001C30, V500R001C60SPC500, and V500R005C00SPC100 Secospace USG6600 and USG9500 versions V500R001C30SPC200, V500R001C30SPC600, V500R001C60SPC500, and V500R005C00SPC100

Description The issue is related to an information leakage vulnerability that can be exploited by sending specific request packets to affected devices, potentially leading to information leakage. It is also associated with incorrect clearance or release of resources, which can cause a denial of service when a specific message is handled incorrectly by the IPSec Module, resulting in unreleased memory.

Recommendations For Huawei NIP6800 versions V500R001C30, V500R001C60SPC500, and V500R005C00SPC100, restrict access to the IPSec Module to minimize the risk of exploitation. For Secospace USG6600 and USG9500 versions V500R001C30SPC200, V500R001C30SPC600, V500R001C60SPC500, and V500R005C00SPC100, avoid using the IPSec Module until a fix is available. As a temporary workaround, consider disabling the IPSec Module until a patch is available.
