Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Path traversal (CVE-ID: CVE-2021-29425)
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error within the FileNameUtils.normalize method when processing directory traversal sequences, such as "//../foo", or "\..foo". A remote attacker can send a specially crafted request and verify files availability in the parent folder.
2) Improper input validation (CVE-ID: CVE-2022-21616)
The vulnerability allows a local privileged user to read and manipulate data.
The vulnerability exists due to improper input validation within the Web Container component in Oracle WebLogic Server. A local privileged user can exploit this vulnerability to read and manipulate data.
3) Security features bypass (CVE-ID: CVE-2022-22968)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to patterns for disallowedFields on a DataBinder are case sensitive, which means a field is not effectively protected unless it is listed
with both upper and lower case for the first character of the field,
including upper and lower case for the first character of all nested
fields within the property path. A remote attacker can bypass implemented security restrictions by passing case sensitive data to the application.
4) Incorrect default permissions (CVE-ID: CVE-2020-17521)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to incorrect default permissions for temporary files and folders that are set by the application. A local user with access to the system can view contents of files and directories or modify them.
5) Input validation error (CVE-ID: CVE-2022-22971)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input within the Spring application with a STOMP over WebSocket endpoint. A remote user can pass specially crafted input to the application and perform a denial of service (DoS) attack.
6) Infinite loop (CVE-ID: CVE-2022-23437)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop when parsing XML documents. A remote attacker can supply a specially crafted XML document, consume all available system resources and cause denial of service conditions.
7) Comparison using wrong factors (CVE-ID: CVE-2020-28052)
The vulnerability allows a remote attacker to brute-force password hashes.
The vulnerability exists due to comparison error in OpenBSDBCrypt.checkPassword() function in core/src/main/java/org/bouncycastle/crypto/generators/OpenBSDBCrypt.java when matching passwords with hashes. A remote attacker can pass an incorrect password that will be accepted as a valid one by the library, bypass authentication process and gain unauthorized access to the application that uses vulnerable version of Bouncy Castle.
