Description

This security bulletin contains information about 5 secuirty vulnerabilities.


1) Input validation error (CVE-ID: CVE-2021-22060)

The vulnerability allows a remote attacker to modify existing log records.

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can pass specially crafted input to the application and modify existing log records.


2) Incorrect Regular Expression (CVE-ID: CVE-2022-22950)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due improper input validation when processing SpEL expressions. A remote attacker can send a specially crafted HTTP request to the affected application and perform a denial of service (DoS) attack.


3) Improper Authentication (CVE-ID: CVE-2022-0547)

The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to an error when processing authentication requests in external authentication plug-ins when more than one of them makes use of deferred authentication replies. A remote attacker can bypass authentication process and gain unauthorized access to the network with only partially correct credentials.


4) Infinite loop (CVE-ID: CVE-2022-0778)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to infinite loop within the BN_mod_sqrt() function when processing an ASN.1 certificate that contains elliptic curve public keys in compressed form or explicit elliptic curve parameters with a base point encoded in compressed form. A remote attacker can supply a specially crafted certificate to the TLS server or client, consume all available system resources and cause denial of service conditions.


5) Code Injection (CVE-ID: CVE-2022-22965)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to improper input validation. A remote attacker can send a specially crafted HTTP request to the affected application and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Note, the vulnerability is being actively exploited in the wild.

This vulnerability was dubbed "Spring4Shell".
