odt2spip < 4.4.0 OS Command Injection via Document Filename
odt2spip plugin for SPIP before 4.4.0 contains an OS command injection vulnerability that allows authenticated authors to execute arbitrary commands by uploading a document with a maliciously crafted filename through the document import form. Attackers can embed shell metacharacters such as $(id) in a non-.odt filename, which survives insufficient sanitization in odt2spip_deplacer_fichier_upload() and LibreOffice::createCommand(), to achieve remote code execution as the web-server user during the LibreOffice conversion process.
SPIP before 4.4.18 SSRF via HTTP Redirects in recuperer_url
SPIP before 4.4.18 contains a server-side request forgery vulnerability in recuperer_url() in ecrire/inc/distant.php that follows up to 10 redirects without re-validating targets with valider_url_distante(). Authenticated attackers can supply a remote URL, such as a syndicated site feed or remote document, that redirects to internal or link-local addresses including cloud metadata endpoints.
SPIP < 4.4.18 Code Injection via Navigation Endpoint on SQLite
SPIP before 4.4.18 contains a code injection vulnerability in SQLite-backed installations. The navigation menu endpoint improperly handles array-typed user input, which bypasses input sanitization and allows the value to break out of an internal quoted string context when evaluated as PHP. An authenticated attacker with at minimum editor (redacteur) privileges can submit a single crafted GET request to /ecrire/?exec=navigation to execute arbitrary OS commands in the web server process. MySQL-backed installations are not affected.
SPIP versions prior to 4.4.14 contain a remote code execution vulnerability in the public space that is limited to certain nginx configurations, allowing attackers to execute arbitrary code in the context of the web server. Attackers can exploit this vulnerability through specific nginx configuration scenarios to achieve code execution, and this issue is not mitigated by the SPIP security screen.
SPIP < 4.4.14 Remote Code Execution via Private Space
SPIP versions prior to 4.4.14 contain a remote code execution vulnerability in the private space that allows attackers to execute arbitrary code in the context of the web server. Attackers can exploit this vulnerability to achieve code execution that bypasses the SPIP security screen protections.
SPIP 4.4.10 through 4.4.12 before 4.4.13 allows unintended privilege assignment (of administrator privileges) during the editing of an author data structure because of STATUT mishandling.
SPIP < 4.4.10 Authentication Bypass via PHP Type Juggling
SPIP versions prior to 4.4.10 contain an authentication bypass vulnerability caused by PHP type juggling that allows unauthenticated attackers to access protected information. Attackers can exploit loose type comparisons in authentication logic to bypass login verification and retrieve sensitive internal data.
SPIP < 4.4.10 SQL Injection RCE via Union & PHP Tags
SPIP versions prior to 4.4.10 contain a SQL injection vulnerability that allows authenticated low-privilege users to execute arbitrary SQL queries by manipulating union-based injection techniques. Attackers can exploit this SQL injection flaw combined with PHP tag processing to achieve remote code execution on the server.
Spip 4.1.10 Admin Account Spoofing via Malicious SVG Upload
Spip 4.1.10 contains a file upload vulnerability that allows attackers to upload malicious SVG files with embedded external links. Attackers can trick administrators into clicking a crafted SVG logo that redirects to a potentially dangerous URL through improper file upload filtering.
A cross-site scripting (XSS) vulnerability in the Article module of SPIP v4.3.3 allows authenticated attackers to execute arbitrary web scripts or HTML via injecting a crafted payload into the Title parameter.
An authenticated arbitrary file upload vulnerability in the Documents module of SPIP v4.3.3 allows attackers to execute arbitrary code via uploading a crafted PDF file.
svg-sanitizer is a SVG/XML sanitizer written in PHP. A cross-site scripting vulnerability impacts all users of the `svg-sanitizer` library prior to version 0.15.0. This issue is fixed in version 0.15.0. There is currently no workaround available.
