CVSS v3.1 |
| A flaw was found in MRTG. When the MRTG daemon is started as a root user and subsequently drops privileges, a local, low-privileged attacker can exploit a symbolic link (symlink) following vulnerability. By influencing or pre-placing a symlink in the process ID (PID) file path, the attacker can trick the root process into changing the ownership of an arbitrary existing file to the daemon user. This can lead to local privilege escalation, allowing unauthorized access to or modification of sensitive files. |
| Link following in CredentialProvider in Google Chrome on on Windows prior to 151.0.7922.169 allowed a local attacker to potentially execute arbitrary code outside the sandbox via a local program. (Chromium security severity: High) |
| SSHFS is a network filesystem client for connecting to SSH servers. Prior to version 3.7.6, a rogue SFTP server can return absolute symlink targets or relative targets containing parent-directory components that SSHFS passes through FUSE for resolution by the client kernel against the local filesystem. The documented transform_symlinks mitigation does not contain relative targets because transform_symlink() returns early at sshfs.c:2181, while sshfs_readlink() at sshfs.c:2234 to sshfs.c:2236 otherwise copies the server-supplied link target to the kernel. A victim or victim-side tool that follows such a link through ordinary operations such as cp, rsync, backup tooling, or an editor can disclose readable local files back to the server or write server-controlled content to writable local files, potentially including startup or scheduled-task files. This issue is fixed in version 3.7.6. |
| Grav API Plugin is a RESTful API for Grav CMS that provides full headless access to your site's content. Prior to 1.0.0-rc.16, the Grav API plugin JwtAuthenticator::extractBearerToken() accepts a JWT from the token URL query parameter on every /api/v1 route, including state-changing endpoints. Request URLs consequently expose valid access tokens through Apache, proxy, and CDN logs, browser history, and Referer headers, allowing a party with access to those records to reuse the token with the owner's API privileges. This issue is fixed in version 1.0.0-rc.16. |
| BBOT's unarchive module rejects archives containing symlink entries before extraction, but for zip and 7z archives it failed to detect symlinks whose listing carries a DOS-attribute prefix before the unix mode, as produced by legacy versions of p7zip. Such an archive, downloaded and extracted during a scan (for example via filedownload), bypassed the guard and caused an attacker-controlled symlink to be written into the extraction directory. The effect is limited to planting the symlink (its target is not written through), and only hosts using such a legacy p7zip build are affected; current mainline 7-Zip is not. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: nl80211: free RNR data on MBSSID mismatch
nl80211_parse_beacon() rejects EMA RNR data when there are fewer RNR
entries than MBSSID entries.
The rejected RNR allocation has not been attached to the beacon data yet,
so free it before returning the error. |
| Windows Update Stack Elevation of Privilege Vulnerability |
| An elevation of privilege vulnerability exists in Microsoft Windows when Folder redirection has been enabled via Group Policy. When folder redirection file server is co-located with Terminal server, an attacker who successfully exploited the vulnerability would be able to begin redirecting another user's personal data to a created folder.
To exploit the vulnerability, an attacker can create a new folder under the Folder Redirection root path and create a junction on a newly created User folder. When the new user logs in, Folder Redirection would start redirecting to the folder and copying personal data.
This elevation of privilege vulnerability can only be addressed by reconfiguring Folder Redirection with Offline files and restricting permissions, and NOT via a security update for affected Windows Servers. See the FAQ section of this CVE for configuration guidance. |

| Windows Update Service Elevation of Privilege Vulnerability |
| Windows Installer Elevation of Privilege Vulnerability |
| Windows 10 Update Assistant Elevation of Privilege Vulnerability |
| Windows Installer Elevation of Privilege Vulnerability |
| A flaw was found in GNU tar. When extracting an archive with the --one-top-level option, hardlink targets are not confined to the designated top-level directory and may resolve relative to the extraction working directory. A crafted archive can create hardlinks that escape the intended boundary and, when combined with a preexisting symbolic link under the working directory, may allow writing outside that boundary during a single extraction. |
| PAX Technology Q80 AIP File Parsing Link Following Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of PAX Technology Q80. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the parsing of AIP files. By creating a symbolic link, an attacker can abuse the installer process to write arbitrary files. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of root. Was ZDI-CAN-30583. |
| Improper link resolution before file access ('link following') in Windows DHCP Server allows an authorized attacker to elevate privileges locally. |
| Improper link resolution before file access ('link following') in Windows DHCP Server allows an authorized attacker to elevate privileges locally. |
| Improper link resolution before file access ('link following') in Windows DHCP Server allows an authorized attacker to elevate privileges locally. |
| Improper link resolution before file access ('link following') in Windows DHCP Server allows an authorized attacker to elevate privileges locally. |
| Improper link resolution before file access ('link following') in Microsoft OneDrive allows an authorized attacker to elevate privileges locally. |
