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 incomplete fix for SB2019020812 when processing HTTP/2 requests. A remote attacker can perform denial of service attack by not sending WINDOW_UPDATE messages for the connection window (stream 0).
2) Deserialization of untrusted data (CVE-ID: CVE-2017-5645)
CWE-ID: CWE-502 - Deserialization of Untrusted Data
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists receiving serialized log events from another application when using the TCP socket server or UDP socket server. A remote attacker can submit a specially crafted binary payload, when deserialized, and execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
3) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2019-14379)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:L/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code on a targeted system.
The vulnerability exists due to the "SubTypeValidator.java" file mishandles default typing when Ehcache is used. A remote attacker can send a request that submits malicious input to the targeted system and execute arbitrary code.
