CWE-59BaseDraft
Improper Link Resolution Before File Access ('Link Following')
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.

CVE-2024-28189Judge0 is an open-source online code execution system. The application uses the UNIX chown command on an untrusted file within the sandbox. An attacker can abuse this by creating a symbolic link (symlink) to a file outside the sandbox, allowing the attacker to run chown on arbitrary files outside of the sandbox. This vulnerability is not impactful on it's own, but it can be used to bypass the patch for CVE-2024-28185 and obtain a complete sandbox escape. This vulnerability is fixed in 1.13.1.
CVE-2024-28185Judge0 is an open-source online code execution system. The application does not account for symlinks placed inside the sandbox directory, which can be leveraged by an attacker to write to arbitrary files and gain code execution outside of the sandbox. When executing a submission, Judge0 writes a `run_script` to the sandbox directory. The security issue is that an attacker can create a symbolic link (symlink) at the path `run_script` before this code is executed, resulting in the `f.write` writing to an arbitrary file on the unsandboxed system. An attacker can leverage this vulnerability to overwrite scripts on the system and gain code execution outside of the sandbox.
CVE-2014-4480Directory traversal vulnerability in afc in AppleFileConduit in Apple iOS before 8.1.3 and Apple TV before 7.0.3 allows attackers to access unintended filesystem locations by creating a symlink.
CVE-2002-2374Unspecified vulnerability in pprosetup in Sun PatchPro 2.0 has unknown impact and attack vectors related to "unsafe use of temporary files."
CVE-2026-7374A flaw was found in KubeVirt's virt-handler component. This vulnerability allows an authenticated OpenShift user with edit permissions in a single namespace to exploit improper symlink validation when connecting to virtual machine console sockets. By replacing the console socket with a symlink to the host's container runtime (CRI-O) socket, an attacker can hijack virt-handler's privileged connection. This enables the attacker to access any Unix socket on the host, potentially leading to full control of the node and the entire cluster.
CVE-2018-5225In browser editing in Atlassian Bitbucket Server from version 4.13.0 before 5.4.8 (the fixed version for 4.13.0 through 5.4.7), 5.5.0 before 5.5.8 (the fixed version for 5.5.x), 5.6.0 before 5.6.5 (the fixed version for 5.6.x), 5.7.0 before 5.7.3 (the fixed version for 5.7.x), and 5.8.0 before 5.8.2 (the fixed version for 5.8.x), allows authenticated users to gain remote code execution using the in browser editing feature via editing a symbolic link within a repository.
CVE-2025-43220This issue was addressed with improved validation of symlinks. This issue is fixed in iPadOS 17.7.9, macOS Sequoia 15.6, macOS Sonoma 14.7.7, macOS Ventura 13.7.7. An app may be able to access protected user data.
CVE-2025-30457This issue was addressed with improved validation of symlinks. This issue is fixed in macOS Ventura 13.7.5, macOS Sequoia 15.4, macOS Sonoma 14.7.5. A malicious app may be able to create symlinks to protected regions of the disk.
CVE-2024-6868mudler/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.
CVE-2024-37143Dell PowerFlex appliance versions prior to IC 46.381.00 and IC 46.376.00, Dell PowerFlex rack versions prior to RCM 3.8.1.0 (for RCM 3.8.x train) and prior to RCM 3.7.6.0 (for RCM 3.7.x train), Dell PowerFlex custom node using PowerFlex Manager versions prior to 4.6.1.0, Dell InsightIQ versions prior to 5.1.1, and Dell Data Lakehouse versions prior to 1.2.0.0 contain an Improper Link Resolution Before File Access vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability to execute arbitrary code on the system.
