Description

This security bulletin contains information about 5 secuirty vulnerabilities.

1) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2022-34165)

The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.

The vulnerability exists due to improper validation of HTTP requests. 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) Input validation error (CVE-ID: CVE-2022-3509)

The vulnerability exists due to insufficient validation of user-supplied input when parsing textformat data. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.

3) Input validation error (CVE-ID: CVE-2022-3171)

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 containing multiple instances of non-repeated embedded messages with repeated or unknown fields. A remote attacker can cause objects to be converted back-n-forth between mutable and immutable forms, resulting in potentially long garbage collection pauses.

4) Resource exhaustion (CVE-ID: CVE-2022-37734)

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

The vulnerability exists due to application does not properly control consumption of internal resources. A remote attacker can trigger send a specially crafted GraphQL query and consume available CPU resources, resulting in a denial of service.

5) Improper input validation (CVE-ID: CVE-2022-24839)

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

The vulnerability exists due to improper input validation within the Centralized Third Party Jars (NekoHTML) component in Oracle WebLogic Server. A remote non-authenticated attacker can exploit this vulnerability to perform a denial of service (DoS) attack.
