Threat metrics

Exploit Maturity: POC

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction: Passive: Successful exploitation of this vulnerability requires limited interaction by the targeted user with the vulnerable system and the attacker’s payload. These interactions would be considered involuntary and do not require that the user actively subvert protections built into the vulnerable system.
Vulnerable system confidentiality: None: There is no loss of confidentiality within the Vulnerable System.
Vulnerable system integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact to the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), CVSS vector, the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Given the absence of official patches, European organizations should implement the following specific mitigations: 1) Employ strict input validation and output encoding on the login page parameters if possible by customizing or wrapping the WebSSH application, to neutralize malicious scripts in 'hostname' and 'port' inputs. 2) Use web application firewalls (WAFs) with rules specifically designed to detect and block XSS payloads targeting WebSSH login pages. 3) Restrict access to the WebSSH interface to trusted IP addresses or VPNs to reduce exposure to external attackers. 4) Educate users and administrators about the risks of phishing and social engineering attacks that could exploit this vulnerability. 5) Monitor web server and application logs for suspicious requests containing unusual or script-like content in the 'hostname' or 'port' parameters. 6) Consider deploying Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in browsers accessing the WebSSH interface. 7) Plan for rapid patch deployment once the vendor releases an official fix, and track updates from security advisories related to Huashengdun WebSSH.

Description

A vulnerability, which was classified as problematic, has been found in Huashengdun WebSSH up to 1.6.2. Affected by this issue is some unknown functionality of the component Login Page. The manipulation of the argument hostname/port leads to cross site scripting. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

For European organizations using Huashengdun WebSSH, this vulnerability poses a moderate risk primarily to the confidentiality and integrity of user sessions. Since WebSSH is a web-based SSH client, it is often used by IT administrators and security teams to manage remote servers. Successful exploitation could allow attackers to steal session cookies, credentials, or perform actions on behalf of the user, potentially leading to unauthorized access to critical infrastructure. This risk is heightened in sectors with high reliance on remote server management, such as finance, telecommunications, and government agencies. The lack of vendor response and absence of patches mean organizations must rely on mitigations until an official fix is available. The requirement for user interaction suggests that phishing or social engineering campaigns could be used to exploit this vulnerability, increasing the risk in environments where users are less security-aware. Additionally, the vulnerability could be leveraged as a foothold for more advanced attacks targeting European critical infrastructure or data centers.

Summary

CVE-2025-7885 is a cross-site scripting (XSS) vulnerability identified in Huashengdun WebSSH versions up to 1.6.2. The vulnerability resides in the login page component, specifically in the handling of the 'hostname' and 'port' parameters. Improper input validation or sanitization allows an attacker to inject malicious scripts into these parameters, which are then executed in the context of the victim's browser when the login page is accessed. This vulnerability is remotely exploitable without requiring authentication, and the attacker only needs to trick a user into visiting a crafted URL or interacting with a manipulated login page. The CVSS 4.0 base score is 5.3, indicating a medium severity level. The vector details show that the attack requires no privileges and no user authentication but does require user interaction (UI:P). The impact on confidentiality is none, integrity is low, and availability is none, as the primary risk is the execution of malicious scripts that could lead to session hijacking, credential theft, or other client-side attacks. The vendor was notified but did not respond, and no patches have been released yet. Although no known exploits are currently in the wild, the public disclosure of the exploit code increases the risk of exploitation.
