CVE-2015-8677 describes a memory leak vulnerability in various Huawei S-series Campus switches, including S5300, S2350, S9300, and S5720 models running specific software versions. This flaw allows remote authenticated users to trigger a denial of service (DoS) by repeatedly logging in and out of the HTTPS or SFTP server, leading to memory exhaustion and device restarts due to unreleased SSL session information. The vulnerability carries a CVSS v3.0 score of 6.5 (Medium), indicating that an attacker with low privileges can exploit it over the network with low attack complexity, resulting in high availability impact. There is no impact on confidentiality or integrity. Currently, there is no known active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE. Its EPSS score is very low, suggesting a minimal likelihood of exploitation in the wild.
