Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Deserialization of Untrusted Data (CVE-ID: CVE-2023-39410)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to reader can consume memory beyond the allowed constraints and thus lead to out of memory on the system, when deserializing untrusted or corrupted data. A remote attacker can pass specially crafted data to the application and perform a denial of service attack.
2) Input validation error (CVE-ID: CVE-2023-34054)
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. A remote attacker can send specially crafted HTTP requests to the application and perform a denial of service (DoS) attack.
3) SQL injection (CVE-ID: CVE-2024-1597)
The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.
The vulnerability exists due to insufficient sanitization of user-supplied data when using the "PreferQueryMode=SIMPLE" option. A remote attacker can send a specially crafted request to the affected application and execute arbitrary SQL commands within the application database.
Successful exploitation of this vulnerability may allow a remote attacker to read, delete, modify data in database and gain complete control over the affected application.
4) 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.
5) Path traversal (CVE-ID: CVE-2023-34062)
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences. A remote attacker can send a specially crafted HTTP request and read arbitrary files on the system.
Successful exploitation of the vulnerability requires that Reactor Netty HTTP Server is configured to serve static resources.
6) Resource exhaustion (CVE-ID: CVE-2023-44487)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improperly control of consumption for internal resources when handling HTTP/2 requests with compressed HEADERS frames. A remote attacker can send a sequence of compressed HEADERS frames followed by RST_STREAM frames and perform a denial of service (DoS) attack, a.k.a. "Rapid Reset".
Note, the vulnerability is being actively exploited in the wild.
