CVE-2022-21647 1 Codeigniter 1 Codeigniter 2022-01-20 7.5 HIGH 9.8 CRITICAL
CodeIgniter is an open source PHP full-stack web framework. Deserialization of Untrusted Data was found in the `old()` function in CodeIgniter4. Remote attackers may inject auto-loadable arbitrary objects with this vulnerability, and possibly execute existing PHP code on the server. We are aware of a working exploit, which can lead to SQL injection. Users are advised to upgrade to v4.1.6 or later. Users unable to upgrade as advised to not use the `old()` function and form_helper nor `RedirectResponse::withInput()` and `redirect()->withInput()`.
CVE-2018-12071 1 Codeigniter 1 Codeigniter 2018-08-10 7.5 HIGH 9.8 CRITICAL
A Session Fixation issue exists in CodeIgniter before 3.1.9 because session.use_strict_mode in the Session Library was mishandled.
CVE-2015-5725 1 Codeigniter 1 Codeigniter 2018-03-14 7.5 HIGH 9.8 CRITICAL
SQL injection vulnerability in the offset method in the Active Record class in CodeIgniter before 2.2.4 allows remote attackers to execute arbitrary SQL commands via vectors involving the offset variable.
CVE-2014-8684 2 Codeigniter, Kohanaframework 2 Codeigniter, Kohana 2017-09-28 7.5 HIGH 9.8 CRITICAL
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.
CVE-2014-8686 1 Codeigniter 1 Codeigniter 2017-09-28 5.0 MEDIUM 9.8 CRITICAL
CodeIgniter before 2.2.0 makes it easier for attackers to decode session cookies by leveraging fallback to a custom XOR-based encryption scheme when the Mcrypt extension for PHP is not available.
CVE-2016-10131 1 Codeigniter 1 Codeigniter 2017-03-16 7.5 HIGH 9.8 CRITICAL
system/libraries/Email.php in CodeIgniter before 3.1.3 allows remote attackers to execute arbitrary code by leveraging control over the email->from field to insert sendmail command-line arguments.
