Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) Input validation error (CVE-ID: CVE-2023-20861)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of SpEL expressions. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
2) Insufficient verification of data authenticity (CVE-ID: CVE-2021-37533)
The vulnerability allows an attacker to redirect victim to a malicious host.
The vulnerability exists due to the application trusts the host from PASV response by default. A remote attacker can trick the victim into connecting to an attacker controlled FTP server and then redirect the application to another host.
3) Code Injection (CVE-ID: CVE-2022-42890)
The vulnerability allows a remote user to gain access to sensitive information.
The vulnerability exists due to the application allows running Java classes via JavaScript. A remote user can use JavaScript to execute a Java class on the system and obtain its execution results.
Example:
Runtime.getRuntime().exec("xxx");
4) 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.
5) Deserialization of Untrusted Data (CVE-ID: CVE-2022-42003)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insecure input validation when processing serialized data when the UNWRAP_SINGLE_VALUE_ARRAYS feature is enabled. A remote attacker can pass specially crafted data to the application and cause a denial of service condition on the target system.
6) Input validation error (CVE-ID: CVE-2022-41966)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied XML input. A remote attacker can pass specially crafted data to the application, trigger a stack overflow error and perform a denial of service (DoS) attack.
7) Infinite loop (CVE-ID: CVE-2022-41881)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop within the HaProxyMessageDecoder when parsing a TLV with type of "PP2_TYPE_SSL". A remote attacker can pass a specially crafted message to consume all available system resources and cause denial of service conditions.
8) Uncontrolled Recursion (CVE-ID: CVE-2023-1436)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to uncontrolled recursion when constructing a JSONArray from a Collection that contains a self-reference in one of its elements. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
9) Deserialization of Untrusted Data (CVE-ID: CVE-2022-45047)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data within the org.apache.sshd.server.keyprovider.SimpleGeneratorHostKeyProvider class. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
