Description
This security bulletin contains information about 13 secuirty vulnerabilities.
1) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2025-54155)
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to allocation of resources without limits or throttling. A remote administrator can pass specially crafted input to the application and perform a denial of service (DoS) attack.
2) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2025-54161)
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to allocation of resources without limits or throttling. A remote administrator can pass specially crafted input to the application and perform a denial of service (DoS) attack.
3) Path traversal (CVE-ID: CVE-2025-54162)
The vulnerability allows a remote user to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences. A remote administrator can send a specially crafted HTTP request and read arbitrary files on the system.
4) Path traversal (CVE-ID: CVE-2025-62853)
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 user can send a specially crafted HTTP request and read arbitrary files on the system.
5) Path traversal (CVE-ID: CVE-2025-66278)
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 user can send a specially crafted HTTP request and read arbitrary files on the system.
6) Path traversal (CVE-ID: CVE-2026-22894)
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 user can send a specially crafted HTTP request and read arbitrary files on the system.
7) Path traversal (CVE-ID: CVE-2025-62855)
The vulnerability allows a local user to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences. A local administrator can send a specially crafted HTTP request and read arbitrary files on the system.
8) Path traversal (CVE-ID: CVE-2025-62856)
The vulnerability allows a local user to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences. A local administrator can send a specially crafted HTTP request and read arbitrary files on the system.
9) NULL pointer dereference (CVE-ID: CVE-2025-54163)
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error. A remote administrator can pass specially crafted data to the application and perform a denial of service (DoS) attack.
10) Out-of-bounds read (CVE-ID: CVE-2025-54169)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition. A remote user can trigger an out-of-bounds read error and read contents of memory on the system.
11) Code Injection (CVE-ID: CVE-2025-57707)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to improper neutralization of directives in statically saved code. A remote user can execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
12) Improper Authentication (CVE-ID: CVE-2025-57713)
The vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to an error when processing authentication requests. A remote attacker can bypass authentication process and gain unauthorized access to sensitive information.
13) Resource exhaustion (CVE-ID: CVE-2025-62854)
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. A remote user can trigger resource exhaustion and perform a denial of service (DoS) attack.
