Description
This security bulletin contains information about 11 secuirty vulnerabilities.
1) Improper Authorization (CVE-ID: CVE-2024-38827)
The vulnerability allows a remote attacker to bypass authorization.
The vulnerability exists due to presence of Locale dependent exceptions when using String.toLowerCase() and String.toUpperCase() for string comparison. A remote attacker can bypass authorization rules using specially crafted input.
Note, the vulnerability is related to #VU98795 (CVE-2024-38820).
2) Improper input validation (CVE-ID: CVE-2025-50059)
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
The vulnerability exists due to improper input validation within the Networking component in Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to gain access to sensitive information.
3) Cleartext storage of sensitive information (CVE-ID: CVE-2025-36017)
The vulnerability allows a remote user to gain access to potentially sensitive information.
The vulnerability exists due to IBM Controller stores unencrypted sensitive information in environmental variables files. A remote user can gain unauthorized access to sensitive information on the system.
4) Input validation error (CVE-ID: CVE-2024-38828)
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 passed via Spring MVC controller method with @RequestBody byte[] parameter. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
5) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2015-1673)
The vulnerability allows a remote attacker to escalate privileges on the system.
The vulnerability exists due to application does not properly impose security restrictions. A remote attacker can trigger the vulnerability to bypass security restrictions and escalate privileges on the system.
6) Key management errors (CVE-ID: CVE-2024-31033)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application. The vulnerability has unknown impact and attack vector.
7) Heap-based buffer overflow (CVE-ID: CVE-2025-2900)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a defect in its native AES/CBC encryption implementation. A remote attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
8) Improper input validation (CVE-ID: CVE-2025-30698)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
The vulnerability exists due to improper input validation within the 2D component in Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to read and manipulate data.
9) Improper input validation (CVE-ID: CVE-2025-21587)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
The vulnerability exists due to improper input validation within the JSSE component in Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to read and manipulate data.
10) Security features bypass (CVE-ID: CVE-2022-22968)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to patterns for disallowedFields on a DataBinder are case sensitive, which means a field is not effectively protected unless it is listed
with both upper and lower case for the first character of the field,
including upper and lower case for the first character of all nested
fields within the property path. A remote attacker can bypass implemented security restrictions by passing case sensitive data to the application.
11) Security features bypass (CVE-ID: CVE-2024-38820)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to String.toLowerCase() has some Locale dependent exceptions when handling case insensitive patterns in DataBinder. A remote attacker can bypass implemented security restrictions by passing specially crafted data to the application.
