codeigniter/framework SQL injection in ODBC database driver
CodeIgniter 3.1.0 addressed a critical security issue within the ODBC database driver. This update includes crucial fixes to mitigate a SQL injection vulnerability, preventing potential exploitation by attackers. It is noteworthy that these fixes render the query builder and escape() functions incompatible with the ODBC driver. However, the update introduces actual query binding as a more secure alternative.
Inadequate XSS Prevention in CodeIgniter/Framework Security Library
The xss_clean() method in the Security Library of CodeIgniter/Framework, specifically in versions before 3.0.3, exhibited a vulnerability that allowed certain Cross-Site Scripting (XSS) vectors to bypass its intended protection mechanisms.
The xss_clean() method is designed to sanitize input data by removing potentially malicious content, thus preventing XSS attacks. However, in versions prior to 3.0.3, it was discovered that the method did not adequately mitigate specific XSS vectors, leaving a potential security gap.
CodeIgniter before 3.0 and Kohana 3.2.3 and earlier and 3.3.x through 3.3.2 make it easier for remote attackers to spoof session cookies and consequently conduct PHP object injection attacks by leveraging use of standard string comparison operators to compare cryptographic hashes.
