Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Input validation error (CVE-ID: CVE-2021-20329)
The vulnerability allows a remote attacker to manipulate data
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can inject additional fields into marshalled documents and manipulate data in the database.
2) Code Injection (CVE-ID: CVE-2022-42889)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to an insecure variable interpolation when processing untrusted input. A remote attacker can send a specially crafted input and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
Note, the vulnerability was dubbed Text4shell.
3) Type Confusion (CVE-ID: CVE-2023-0286)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a type confusion error related to X.400 address processing inside an X.509 GeneralName. A remote attacker can pass specially crafted data to the application, trigger a type confusion error and perform a denial of service (DoS) attack or read memory contents.
In most cases, the attack requires the attacker to provide both the certificate chain and CRL, neither of which need to have a valid signature. If the attacker only controls one of these inputs, the other input must already contain an X.400 address as a CRL distribution point, which is uncommon. As such, this vulnerability is most likely to only affect applications which have implemented their own functionality for retrieving CRLs over a network.
4) Out-of-bounds write (CVE-ID: CVE-2023-0767)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing PKCS 12 Safe Bag attributes. A remote attacker can create a specially crafted PKCS 12 cert bundle, trick the victim into loading it, trigger an out-of-bounds write and execute arbitrary code on the target system.
