{"id":"CVE-2026-47116","published":"2026-09-22T20:17:03.583","lastModified":"2026-09-24T21:08:55.030","description":"LTSecurity LTK3500SF contains a hard-coded credentials vulnerability where the root and guest account passwords are stored in /etc/shadow as weak hashes recoverable with dictionary-based cracking tools. The recovered credentials authenticate against the device's Telnet and SSH services and grant root-level access to the operating system. These services are not confirmed to start automatically at boot, so exploitation requires Telnet or SSH to be running, whether enabled by the device configuration or started manually.","cvssScore":9.8,"cvssSeverity":"CRITICAL","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-798"],"vendors":[],"products":[],"references":[{"url":"https://github.com/AndreaLandriscina/Hardcoded-Credentials-in-LTSecurity-LTK3500SF","tags":[]},{"url":"https://www.vulncheck.com/advisories/ltsecurity-ltk3500sf-hard-coded-credentials-via-telnet-ssh","tags":[]}],"exploitRefs":[{"url":"https://github.com/AndreaLandriscina/Hardcoded-Credentials-in-LTSecurity-LTK3500SF","tags":[]}],"hasPoc":true,"ai":{"summary":"The flaw in LTSecurity LTK3500SF involves hard-coded weak credentials, allowing dictionary-based cracking tools to recover root and guest account passwords, which can then be used to gain root-level access via Telnet and SSH services.","exploitability":"Exploitation requires the Telnet or SSH services to be running, making it moderately difficult. Precondition is that the device is accessible over the network.","blast_radius":"If exploited, the attacker can gain full control over the device, potentially leading to data theft, system compromise, and further network penetration.","remediation":"Disable Telnet and SSH services or ensure they are not running at boot. If necessary, upgrade to the latest version of the software, which is not specified in the description.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["auth-bypass","rce","ssh","telnet"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-09-27T08:50:12.070Z"}}
