A link following vulnerability has been reported to affect QuLog Center. If exploited, the vulnerability could allow remote attackers to traverse the file system to unintended locations and read or overwrite the contents of unexpected files. We have already fixed the vulnerability in the following versions: QuLog Center 1.7.0.831 ( 2024/10/15 ) and later QuLog Center 1.8.0.888 ( 2024/10/15 ) and laterShow less

Rclone is a command-line program to sync files and directories to and from different cloud storage providers. Insecure handling of symlinks with --links and --metadata in rclone while copying to local disk allows unprivileged users to indirectly modify ownership and permissions on symlink target files when a superuser or privileged process performs a copy. This vulnerability could enable privilege escalation and unauthorized access to critical system files, compromising system integrity, confidentiality, and availability. This vulnerability is fixed in 1.68.2.Show less

A vulnerability in the web-based management interface of Cisco SD-WAN vManage Software could allow an authenticated, remote attacker to read arbitrary files on the underlying file system of the device. This vulnerability is due to insufficient file scope limiting. An attacker could exploit this vulnerability by creating a specific file reference on the file system and then accessing it through the web-based management interface. A successful exploit could allow the attacker to read arbitrary files from the file system of the underlying operating system.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.Show less

Three vulnerabilities in the CLI of Cisco TelePresence CE and RoomOS could allow an authenticated, local attacker to overwrite arbitrary files on the local file system of an affected device. These vulnerabilities are due to improper access controls on files that are on the local file system. An attacker could exploit these vulnerabilities by placing a symbolic link in a specific location on the local file system of an affected device. A successful exploit could allow the attacker to overwrite arbitrary files on the affected device. To exploit these vulnerabilities, an attacker would need to have a remote support user account. Note: CVE-2023-20092 does not affect Cisco DX70, DX80, TelePresence MX Series, or TelePresence SX Series devices. Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.Show less

A code injection vulnerability in the SecuSUITE Server Web Administration Portal of SecuSUITE versions 5.0.420 and earlier could allow an attacker to potentially inject script commands or other executable content into the server that would run with root privilege.Show less

A path collision and arbitrary code execution vulnerability was identified in GitHub Enterprise Server that allowed container escape to escalate to root via ghe-firejail path. Exploitation of this vulnerability requires Enterprise Administrator access to the GitHub Enterprise Server instance. This vulnerability affected all versions of GitHub Enterprise prior to 3.15 and was fixed in versions 3.14.3, 3.13.6, 3.12.11, and 3.11.17. This vulnerability was reported via the GitHub Bug Bounty program.Show less

mudler/LocalAI version 2.17.1 allows for arbitrary file write due to improper handling of automatic archive extraction. When model configurations specify additional files as archives (e.g., .tar), these archives are automatically extracted after downloading. This behavior can be exploited to perform a 'tarslip' attack, allowing files to be written to arbitrary locations on the server, bypassing checks that normally restrict files to the models directory. This vulnerability can lead to remote code execution (RCE) by overwriting backend assets used by the server.Show less
