5.9 CVE-2025-52997
Brute Force Patch Exploit
File Browser provides a file managing interface within a specified directory and it can be used to upload, delete, preview, rename and edit files. Prior to version 2.34.1, a missing password policy and brute-force protection makes the authentication process insecure. Attackers could mount a brute-force attack to retrieve the passwords of all accounts in a given instance. This issue has been patched in version 2.34.1.

CWE-307 : Improper Restriction of Excessive Authentication Attempts
The product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame. the REST API for a network OS has a high limit for number of connections, allowing brute force password guessing Product does not disconnect or timeout after multiple failed logins. Product does not disconnect or timeout after multiple failed logins. Product does not disconnect or timeout after multiple failed logins. Product does not disconnect or timeout after multiple failed logins. Product does not disconnect or timeout after multiple failed logins. User accounts not disabled when they exceed a threshold; possibly a resultant problem.

Dictionary-based Password Attack
[Determine application's/system's password policy] Determine the password policies of the target application/system. [Select dictionaries] Pick the dictionaries to be used in the attack (e.g. different languages, specific terminology, etc.) [Determine username(s) to target] Determine username(s) whose passwords to crack. [Use dictionary to crack passwords.] Use a password cracking tool that will leverage the dictionary to feed passwords to the system and see if they work. |

Password Brute Forcing
An adversary tries every possible value for a password until they succeed. A brute force attack, if feasible computationally, will always be successful because it will essentially go through all possible passwords given the alphabet used (lower case letters, upper case letters, numbers, symbols, etc.) and the maximum length of the password. [Determine application's/system's password policy] Determine the password policies of the target application/system. [Brute force password] Given the finite space of possible passwords dictated by the password policy determined in the previous step, try all possible passwords for a known user ID until application/system grants access. |

| 560 |
Use of Known Domain Credentials
[Acquire known credentials] The adversary must obtain known credentials in order to access the target system, application, or service. [Determine target's password policy] Determine the password policies of the target system/application to determine if the known credentials fit within the specified criteria. [Attempt authentication] Try each credential until the target grants access. [Impersonate] An adversary can use successful experiments or authentications to impersonate an authorized user or system, or to laterally move within a system or application [Spoofing] Malicious data can be injected into the target system or into a victim user's system by an adversary. The adversary can also pose as a legitimate user to perform social engineering attacks. [Data Exfiltration] The adversary can obtain sensitive data contained within the system or application. |

Password Spraying
[Determine target's password policy] Determine the password policies of the target system/application. [Select passwords] Pick the passwords to be used in the attack (e.g. commonly used passwords, passwords tailored to individual users, etc.) [Brute force password] Given the finite space of possible passwords dictated by information determined in the previous steps, try each password for all known user accounts until the target grants access. |

Credential Stuffing
[Acquire known credentials] The adversary must obtain known credentials in order to access the target system, application, or service. [Determine target's password policy] Determine the password policies of the target system/application to determine if the known credentials fit within the specified criteria. [Attempt authentication] Try each username/password combination until the target grants access. [Impersonate] An adversary can use successful experiments or authentications to impersonate an authorized user or system or to laterally move within a system or application [Spoofing] Malicious data can be injected into the target system or into a victim user's system by an adversary. The adversary can also pose as a legitimate user to perform social engineering attacks. [Data Exfiltration] The adversary can obtain sensitive data contained within the system or application. |

Use of Known Kerberos Credentials
An adversary obtains (i.e. steals or purchases) legitimate Kerberos credentials (e.g. Kerberos service account userID/password or Kerberos Tickets) with the goal of achieving authenticated access to additional systems, applications, or services within the domain. [Acquire known Kerberos credentials] The adversary must obtain known Kerberos credentials in order to access the target system, application, or service within the domain. [Attempt Kerberos authentication] Try each Kerberos credential against various resources within the domain until the target grants access. [Impersonate] An adversary can use successful experiments or authentications to impersonate an authorized user or system, or to laterally move within the domain [Spoofing] Malicious data can be injected into the target system or into other systems on the domain. The adversary can also pose as a legitimate domain user to perform social engineering attacks. [Data Exfiltration] The adversary can obtain sensitive data contained within domain systems or applications. |

| 653 |
Use of Known Operating System Credentials
An adversary guesses or obtains (i.e. steals or purchases) legitimate operating system credentials (e.g. userID/password) to achieve authentication and to perform authorized actions on the system, under the guise of an authenticated user or service. This applies to any Operating System. [Acquire known operating system credentials] The adversary must obtain known operating system credentials in order to access the target system, application, or service within the domain. [Attempt authentication] Try each operating system credential against various systems, applications, and services within the domain until the target grants access. [Impersonate] An adversary can use successful experiments or authentications to impersonate an authorized user or system, or to laterally move within the network [Spoofing] Malicious data can be injected into the target system or into other systems on the network. The adversary can also pose as a legitimate user to perform social engineering attacks. [Data Exfiltration] The adversary can obtain sensitive data contained within system files or application configuration. |
