Description

This security bulletin contains information about 4 vulnerabilities.


1) Improper input validation (CVE-ID: CVE-2022-21338)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote authenticated user to read and manipulate data.

The vulnerability exists due to improper input validation within the General Framework component in Oracle Communications Convergence. A remote authenticated user can exploit this vulnerability to read and manipulate data.


2) Path traversal (CVE-ID: CVE-2021-29425)

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


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.


3) Protection mechanism failure (CVE-ID: CVE-2019-10086)

CWE-ID: CWE-693 - Protection Mechanism Failure

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to bypass certain security restrictions.

The vulnerability exist due to Beanutils is not using by default the a special BeanIntrospector class in PropertyUtilsBean that was supposed to suppress the ability for an attacker to access the classloader via the class property available on all Java objects. A remote attacker can abuse such application behavior against applications that were developed to rely on this security feature.


4) Comparison using wrong factors (CVE-ID: CVE-2020-28052)

CWE-ID: CWE-1025 - Comparison using wrong factors

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber


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.
