In PHP versions 8.2.* before 8.2.31, 8.3.* before 8.3.31, 8.4.* before 8.4.21, and 8.5.* before 8.5.6, when a SOAP server has a typemap configured, the decoding process contains a mistake which checks the wrong variable in case of missing value element. This leads to dereferences a NULL pointer, causing a segmentation fault. This allows a remote unauthenticated attacker to crash the PHP SOAP server process, resulting in denial of service.
A flaw was found in PHP. When a PHP SOAP server has a typemap configured, the apache:Map decoding process checks the incorrect variable in case of a missing value element. This incorrect check leads to a NULL pointer dereference and allows a remote unauthenticated attacker to crash the PHP SOAP server process, resulting in a denial of service.
Отчет
To exploit this issue, a remote unauthenticated attacker needs to send a malicious request to be processed by the apache:Map decoder, causing a crash in the PHP SOAP server process. Due to this reason, this vulnerability has been rated with an important severity.
Меры по смягчению последствий
Red Hat has investigated whether a possible mitigation exists for this issue, and has not been able to identify a practical example. Please update the affected package as soon as possible.
