EUVDB-ID: #VU9464
Risk: Low
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: N/A
CWE-ID:
CWE-120 - Buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists due to buffer overflow in json_decode(). A remote attacker can supply JSON_INVALID_UTF8_IGNORE or JSON_INVALID string, trigger memory corruption and cause the application to crash.
Successful exploitation of the vulnerability results in denial of service.
