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 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 before 4.3.2, 4.2.16, and
4.1.18 is vulnerable to a command injection issue. A
remote and unauthenticated attacker can execute arbitrary operating system commands by sending a crafted multipart file upload HTTP request.
SPIP before 4.1.14 and 4.2.x before 4.2.8 allows XSS via the name of an uploaded file. This is related to javascript/bigup.js and javascript/bigup.utils.js.
ecrire/public/assembler.php in SPIP before 4.1.13 and 4.2.x before 4.2.7 allows XSS because input from _request() is not restricted to safe characters such as alphanumerics.
SPIP v4.1.5 and earlier was discovered to contain a SQL injection vulnerability via the _oups parameter. This vulnerability allows attackers to execute arbitrary code via a crafted POST request.
