CVSS: 9.8EPSS: 1%CPEs: 1EXPL: 1CVE-2023-37460 – Plexus Archiver vulnerable to Arbitrary File Creation in AbstractUnArchiver
https://notcve.org/view.php?id=CVE-2023-37460
Plexis Archiver is a collection of Plexus components to create archives or extract archives to a directory with a unified `Archiver`/`UnArchiver` API. Prior to version 4.8.0, using AbstractUnArchiver for extracting an archive might lead to an arbitrary file creation and possibly remote code execution. When extracting an archive with an entry that already exists in the destination directory as a symbolic link whose target does not exist - the `resolveFile()` function will return the symlink's source instead of its target, which will pass the verification that ensures the file will not be extracted outside of the destination directory. Later `Files.newOutputStream()`, that follows symlinks by default, will actually write the entry's content to the symlink's target. Whoever uses plexus archiver to extract an untrusted archive is vulnerable to an arbitrary file creation and possibly remote code execution. • https://github.com/codehaus-plexus/plexus-archiver/commit/54759839fbdf85caf8442076f001d5fd64e0dcb2 https://github.com/codehaus-plexus/plexus-archiver/releases/tag/plexus-archiver-4.8.0 https://github.com/codehaus-plexus/plexus-archiver/security/advisories/GHSA-wh3p-fphp-9h2m https://access.redhat.com/security/cve/CVE-2023-37460 https://bugzilla.redhat.com/show_bug.cgi?id=2242288 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-61: UNIX Symbolic Link (Symlink) Following •
CVSS: 7.3EPSS: 0%CPEs: 6EXPL: 4CVE-2018-1002200 – plexus-archiver: arbitrary file write vulnerability / arbitrary code execution using a specially crafted zip file
https://notcve.org/view.php?id=CVE-2018-1002200
plexus-archiver before 3.6.0 is vulnerable to directory traversal, allowing attackers to write to arbitrary files via a ../ (dot dot slash) in an archive entry that is mishandled during extraction. This vulnerability is also known as 'Zip-Slip'. plexus-archiver en versiones anteriores a la 3.6.0 es vulnerable a un salto de directorio, lo que permite que los atacantes escriban en archivos arbitrarios mediante un ../ (punto punto barra) en una entrada de archivo que se gestiona de manera incorrecta durante la extracción. Esta vulnerabilidad también se conoce como "Zip-Slip". A path traversal vulnerability has been discovered in plexus-archiver when extracting a carefully crafted zip file which holds path traversal file names. A remote attacker could use this vulnerability to write files outside the target directory and overwrite existing files with malicious code or vulnerable configurations. • https://access.redhat.com/errata/RHSA-2018:1836 https://access.redhat.com/errata/RHSA-2018:1837 https://github.com/codehaus-plexus/plexus-archiver/commit/f8f4233508193b70df33759ae9dc6154d69c2ea8 https://github.com/codehaus-plexus/plexus-archiver/pull/87 https://github.com/snyk/zip-slip-vulnerability https://snyk.io/research/zip-slip-vulnerability https://snyk.io/vuln/SNYK-JAVA-ORGCODEHAUSPLEXUS-31680 https://www.debian.org/security/2018/dsa-4227 https://access.redhat.com/security/cve/CVE-2018- • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
