phpPgAdmin 7.13.0 and earlier contains an incorrect access control vulnerability in sql.php at lines 68-76. The application allows unauthorized manipulation of session variables by accepting user-controlled parameters ('subject', 'server', 'database', 'queryid') without proper validation or access control checks. Attackers can exploit this to store arbitrary SQL queries in $_SESSION['sqlquery'] by manipulating these parameters, potentially leading to session poisoning, stored cross-site scripting, or unauthorized access to sensitive session data.
phpPgAdmin 7.13.0 and earlier contains a SQL injection vulnerability in display.php at line 396. The application passes user-controlled input from $_REQUEST['query'] directly to the browseQuery function without proper sanitization. An authenticated attacker can exploit this vulnerability to execute arbitrary SQL commands through malicious query manipulation, potentially leading to complete database compromise.
phpPgAdmin 7.13.0 and earlier contains a SQL injection vulnerability in dataexport.php at line 118. The application directly executes user-supplied SQL queries from the $_REQUEST['query'] parameter without any sanitization or parameterization via $data->conn->Execute($_REQUEST['query']). An authenticated attacker can exploit this vulnerability to execute arbitrary SQL commands, potentially leading to complete database compromise, data theft, or privilege escalation.
phpPgAdmin 7.13.0 and earlier contains multiple cross-site scripting (XSS) vulnerabilities across various components. User-supplied input from $_REQUEST parameters is reflected in HTML output without proper encoding or sanitization in multiple locations including sequences.php, indexes.php, admin.php, and other unspecified files. An attacker can exploit these vulnerabilities to execute arbitrary JavaScript in victims' browsers, potentially leading to session hijacking, credential theft, or other malicious actions.
phpPgAdmin 7.14.4 and earlier is vulnerable to deserialization of untrusted data which may lead to remote code execution because user-controlled data is directly passed to the PHP 'unserialize()' function in multiple places. An example is the functionality to manage tables in 'tables.php' where the 'ma[]' POST parameter is deserialized.
phppgadmin through 7.12.1 allows sensitive actions to be performed without validating that the request originated from the application. One such area, "database.php" does not verify the source of an HTTP request. This can be leveraged by a remote attacker to trick a logged-in administrator to visit a malicious page with a CSRF exploit and execute arbitrary system commands on the server.
