CWE-611 - Improper Restriction of XML External Entity Reference ('XXE')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to modify information on the system.
The vulnerability exists due to insufficient validation of user-supplied XML input. A remote attacker can pass a specially crafted XML code to the affected application and modify information on the system.
Install update from vendor's website.

EUVDB-ID: #VU60181
Risk: Medium
CVSSv4.0: 5.5 [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:P/U:Green]
CVE-ID: CVE-2021-22569
CWE-ID:
CWE-399 - Resource Management Errors
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the application. protobuf-java allowes the interleaving of
com.google.protobuf.UnknownFieldSet fields in such a way that would be
processed out of order. A small malicious payload can occupy the parser
for several minutes by creating large numbers of short-lived objects
that cause frequent, repeated pauses. A remote attacker can trick the victim into passing specially crafted data to the application and perform a denial of service attack.

EUVDB-ID: #VU56790
Risk: Low
CVSSv4.0: 4.1 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2021-38153
CWE-ID:
CWE-208 - Information Exposure Through Timing Discrepancy
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
the vulnerability exists due to some components in Apache Kafka use "Arrays.equals" to validate a password or key, which is vulnerable to timing attacks. A local user can abuse the "Arrays.equals" to brute force access credentials and escalate privileges on the system.
