The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to infinite loop when processing streams in CopyCoder. A remote attacker can trick the victim into opening a specially crafted archive and perform a denial of service (DoS) attack.


3) Input validation error (CVE-ID: CVE-2024-50602)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input within the XML_ResumeParser function. A remote attacker can pass specially crafted XML input to the application and perform a denial of service (DoS) attack.
