Description
This security bulletin contains information about 11 secuirty vulnerabilities.
1) SQL injection (CVE-ID: CVE-2025-29893)
The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.
The vulnerability exists due to insufficient sanitization of user-supplied data. A remote user 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.
2) SQL injection (CVE-ID: CVE-2025-29894)
The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.
The vulnerability exists due to insufficient sanitization of user-supplied data. A remote user 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.
3) Resource exhaustion (CVE-ID: CVE-2025-29898)
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.
4) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2025-30260)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to allocation of resources without limits. A remote user can cause a denial of service condition on the target system.
5) NULL pointer dereference (CVE-ID: CVE-2025-30275)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error. A remote user can pass specially crafted data to the application and perform a denial of service (DoS) attack.
6) Improper Certificate Validation (CVE-ID: CVE-2025-30277)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to improper certificate validation. A remote user can perform a denial of service (DoS) attack.
7) Improper Certificate Validation (CVE-ID: CVE-2025-30278)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to improper certificate validation. A remote user can perform a denial of service (DoS) attack.
8) Path traversal (CVE-ID: CVE-2025-33033)
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.
9) Path traversal (CVE-ID: CVE-2025-33036)
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.
10) Path traversal (CVE-ID: CVE-2025-33037)
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.
