CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/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 infinite loop when handling recursive expansions. A remote attacker can consume all available system resources and cause denial of service conditions.
2) Improper Certificate Validation (CVE-ID: CVE-2023-34410)
CWE-ID: CWE-295 - Improper Certificate Validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to improper validation of TLS certificate chain, where application does not always consider whether the root of a chain is a configured CA certificate. A remote attacker can perform MitM attack.
3) Buffer overflow (CVE-ID: CVE-2023-37369)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/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 a boundary error when processing XML content in QXmlStreamReader. A remote attacker can pass specially crafted XML input to the application, trigger memory corruption and perform a denial of service (DoS) attack.
