Description
This security bulletin contains information about 10 vulnerabilities.
1) Input validation error (CVE-ID: CVE-2023-26049)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insufficient input validation when parsing cookies. A remote attacker can send a specially crafted HTTP request with a cookie value that starts with a double quote and force the application to read the cookie string until it sees a closing quote. Such behavior can be used to exfiltrate sensitive values from other cookies.
2) NULL pointer dereference (CVE-ID: CVE-2023-28484)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in xmlSchemaFixupComplexType. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
3) Input validation error (CVE-ID: CVE-2023-20863)
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 user can use a specially crafted SpEL expression and perform a denial of service (DoS) attack.
4) Error Handling (CVE-ID: CVE-2023-23931)
The vulnerability allows an attacker to misuse Python API.
The vulnerability exists due to a soundness bug within the Cipher.update_into function, which can allow immutable objects (such as bytes) to be mutated. A malicious programmer can misuse Python API to introduce unexpected behavior into the application.
5) Input validation error (CVE-ID: CVE-2023-28856)
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input. A remote user can use the HINCRBYFLOAT command to create an invalid hash field that will crash Redis on access.
6) 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.
7) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2023-27901)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to Apache Commons FileUpload does not limit the number of request parts within the StaplerRequest. A remote user can initiate a series of uploads and perform a denial of service (DoS) attack.
8) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2023-24998)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to Apache Commons FileUpload does not limit the number of request parts. A remote attacker can initiate a series of uploads and perform a denial of service (DoS) attack.
9) Integer overflow (CVE-ID: CVE-2022-42898)
The vulnerability allows a remote user to execute arbitrary code on the target system.
The vulnerability exists due to an integer overflow within the S4U2Proxy handler on 32-bit systems. A remote user can send specially crafted request to the KDC server, trigger an integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
10) Security features bypass (CVE-ID: CVE-2023-20862)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to the logout support does not properly clean the security context if using serialized versions. A remote attacker can save an empty security context to the HttpSessionSecurityContextRepository and keep users authenticated even after they performed logout.
