Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Uncontrolled Recursion (CVE-ID: CVE-2023-1370)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to uncontrolled recursion when processing nested arrays and objects. A remote attacker can pass specially crafted JSON data to the application and perform a denial of service (DoS) attack.
2) 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.
3) Input validation error (CVE-ID: CVE-2022-3509)
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 when parsing textformat data. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
4) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2023-43642)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to missing upper bound check on chunk length. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
5) Resource exhaustion (CVE-ID: CVE-2023-34462)
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 if no idle timeout handler was configured. A remote attacker can send a client hello packet, which leads the server to buffer up to 16MB of data per connection and results in a denial of service condition.
6) Input validation error (CVE-ID: CVE-2023-32731)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insufficient validation of user-supplied input when parsing HTTP2 requests. When gRPC HTTP2 stack raised a header size exceeded error, it skipped parsing the rest of the HPACK frame. This caused any HPACK table mutations to also be skipped, resulting in a desynchronization of HPACK tables between sender and receiver. This could lead to requests from the proxy being interpreted as containing headers from different proxy clients, leading to an information leak that can be used for privilege escalation or data exfiltration.
7) Improper input validation (CVE-ID: CVE-2022-3510)
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 Policy (Google Protobuf-Java) component in Oracle Communications Cloud Native Core Policy. A remote non-authenticated attacker can exploit this vulnerability to perform a denial of service (DoS) attack.
