Description
This security bulletin contains information about 3 secuirty vulnerabilities.
1) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2021-33037)
The vulnerability allows a remote attacker to preform HTTP request smuggling attacks.
The vulnerability exists due to improper validation of HTTP requests, related to processing of transfer encoding headers. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.
Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.
2) Security restrictions bypass (CVE-ID: CVE-2022-23181)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a time of check, time of use flaw when configured to persist sessions using the FileStore. A local user can perform certain actions which lead to security restrictions bypass and privilege escalation (code execution with Tomcat process privileges).
3) Deserialization of Untrusted Data (CVE-ID: CVE-2020-9484)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data in uploaded files names. A remote attacker can pass specially crafted file name to the application and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system but requires that the server is configured to use PersistenceManager with a FileStore and the attacker knows relative file path from storage location.
