Windows WalletService Elevation of Privilege Vulnerability

VestaCP through 0.9.8-24 allows attackers to gain privileges by creating symlinks to files for which they lack permissions. After reading the RKEY value from user.conf under the /usr/local/vesta/data/users/admin directory, the admin password can be changed via a /reset/?action=confirm&user=admin&code= URI. This occurs because chmod is used unsafely.

AMD fglrx-driver before 15.9 allows local users to gain privileges via a symlink attack. NOTE: This vulnerability exists due to an incomplete fix for CVE-2015-7723.

An issue was discovered in file profile.go in function MemProf in beego through 2.0.2, allows attackers to launch symlink attacks locally.

Windows Installer Elevation of Privilege Vulnerability

An elevation of privilege vulnerability exists when Windows AppX Deployment Service (AppXSVC) improperly handles hard links. An attacker who successfully exploited this vulnerability could run processes in an elevated context. An attacker could then install programs; view, change or delete data. To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and take control of an affected system. The security update addresses the vulnerability by correcting how Windows AppX Deployment Service handles hard links.

An elevation of privilege vulnerability exists in the way the Task Scheduler Service validates certain file operations. An attacker who successfully exploited the vulnerability could gain elevated privileges on a victim system. To exploit the vulnerability, an attacker would require unprivileged code execution on a victim system. The security update addresses the vulnerability by correctly validating file operations.

An elevation of privilege vulnerability exists when the Windows Shell fails to validate folder shortcuts. An attacker who successfully exploited the vulnerability could elevate privileges by escaping a sandbox. To exploit this vulnerability, an attacker would require unprivileged execution on the victim system. The security update addresses the vulnerability by correctly validating folder shortcuts.

An elevation of privilege vulnerability exists in Microsoft Windows when Windows fails to properly handle certain symbolic links, aka 'Windows Elevation of Privilege Vulnerability'. This CVE ID is unique from CVE-2019-0734.

fence_manual, as used in fence 2.02.00-r1 and possibly cman, allows local users to modify arbitrary files via a symlink attack on the fence_manual.fifo temporary file.

systemd-tmpfiles in systemd through 237 mishandles symlinks present in non-terminal path components, which allows local users to obtain ownership of arbitrary files via vectors involving creation of a directory and a file under that directory, and later replacing that directory with a symlink. This occurs even if the fs.protected_symlinks sysctl is turned on.

The chroot, jail, and zone connection plugins in ansible before 1.9.2 allow local users to escape a restricted environment via a symlink attack.

Libcontainer and Docker Engine before 1.6.1 opens the file-descriptor passed to the pid-1 process before performing the chroot, which allows local users to gain privileges via a symlink attack in an image.

Automatic Bug Reporting Tool (ABRT) allows local users to read, change the ownership of, or have other unspecified impact on arbitrary files via a symlink attack on (1) /var/tmp/abrt/*/maps, (2) /tmp/jvm-*/hs_error.log, (3) /proc/*/exe, (4) /etc/os-release in a chroot, or (5) an unspecified root directory related to librpm.

The default event handling scripts in Automatic Bug Reporting Tool (ABRT) allow local users to gain privileges as demonstrated by a symlink attack on a var_log_messages file.

lxc-start in lxc before 1.0.8 and 1.1.x before 1.1.4 allows local container administrators to escape AppArmor confinement via a symlink attack on a (1) mount target or (2) bind mount source.

kernel_crashdump in Apport before 2.19 allows local users to cause a denial of service (disk consumption) or possibly gain privileges via a (1) symlink or (2) hard link attack on /var/crash/vmcore.log.

Comodo Antivirus 12.2.2.8012 has a quarantine flaw that allows privilege escalation. To escalate privilege, a low-privileged attacker can use an NTFS directory junction to restore a malicious DLL from quarantine into the System32 folder.

Vulnerabilities in the Drive Composer allow a low privileged attacker to create and write to a file anywhere on the file system as SYSTEM with arbitrary content as long as the file does not already exist. The Drive Composer installer file allows a low-privileged user to run a "repair" operation on the product.

An issue was discovered in file profile.go in function GetCPUProfile in beego through 2.0.2, allows attackers to launch symlink attacks locally.

Local privilege vulnerability in Yandex Browser for Windows prior to 22.5.0.862 allows a local, low privileged, attacker to execute arbitary code with the SYSTEM privileges through manipulating symlinks to installation file during Yandex Browser update process.

An issue was discovered in Acronis True Image 2020 24.5.22510. anti_ransomware_service.exe includes functionality to quarantine files by copying a suspected ransomware file from one directory to another using SYSTEM privileges. Because unprivileged users have write permissions in the quarantine folder, it is possible to control this privileged write with a hardlink. This means that an unprivileged user can write/overwrite arbitrary files in arbitrary folders. Escalating privileges to SYSTEM is trivial with arbitrary writes. While the quarantine feature is not enabled by default, it can be forced to copy the file to the quarantine by communicating with anti_ransomware_service.exe through its REST API.

UNIX Symbolic Link (Symlink) Following in TP-Link Archer A7(US)_V5_200721 allows an authenticated admin user, with physical access and network access, to execute arbitrary code after plugging a crafted USB drive into the router.

The create_script function in the lxc_container module in Ansible before 1.9.6-1 and 2.x before 2.0.2.0 allows local users to write to arbitrary files or gain privileges via a symlink attack on (1) /opt/.lxc-attach-script, (2) the archived container in the archive_path directory, or the (3) lxc-attach-script.log or (4) lxc-attach-script.err files in the temporary directory.
