Deserialization of Untrusted Data


Severity High
Score 8.8/10


SuiteCRM through 7.12.1 and 8.x through 8.0.1 allows Remote Code Execution. Authenticated users with access to the Scheduled Reports module can achieve this by leveraging PHP deserialization in the email_recipients property. By using a crafted request, they can create a malicious report, containing a PHP-deserialization payload in the email_recipients field. Once someone accesses this report, the backend will deserialize the content of the email_recipients field and the payload gets executed. Project dependencies include a number of interesting PHP deserialization gadgets (e.g., Monolog/RCE1 from phpggc) that can be used for Code Execution.

CWE-502 - Deserialization of Untrusted Data

Deserialization of untrusted data vulnerabilities enable an attacker to replace or manipulate a serialized object, replacing it with malicious data. When the object is deserialized at the victim's end the malicious data is able to compromise the victim’s system. The exploit can be devastating, its impact may range from privilege escalation, broken access control, or denial of service attacks to allowing unauthorized access to the application's internal code and logic which can compromise the entire system.
