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: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
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.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), 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

To mitigate CVE-2025-13058, organizations should immediately apply the official patch identified by commit 002def70b985f7012586df2c44368845bf405ab3 to all affected eXtplorer instances. Beyond patching, administrators should implement strict input validation and output encoding for all user-supplied data, particularly in filename handling components. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers accessing eXtplorer. Regularly audit and monitor web server logs for suspicious requests that may indicate attempted XSS exploitation. Limit access to eXtplorer interfaces to trusted users and networks where possible, and educate users about the risks of clicking unknown links or opening suspicious content. Consider deploying web application firewalls (WAFs) with rules tuned to detect and block XSS payloads targeting eXtplorer. Finally, maintain an up-to-date inventory of software versions and promptly apply security updates to reduce exposure to known vulnerabilities.

Description

A security flaw has been discovered in soerennb eXtplorer up to 2.1.15. The affected element is an unknown function of the component Filename Handler. The manipulation results in cross site scripting. The attack may be launched remotely. The patch is identified as 002def70b985f7012586df2c44368845bf405ab3. Applying a patch is advised to resolve this issue.

Impact

The primary impact of CVE-2025-13058 is the potential execution of arbitrary scripts in the context of users’ browsers interacting with vulnerable eXtplorer instances. This can lead to theft of session tokens, unauthorized actions performed on behalf of users, or redirection to malicious websites, compromising confidentiality and integrity of user sessions. While the vulnerability does not directly affect system availability, successful exploitation could facilitate further attacks such as phishing or malware distribution. Organizations relying on eXtplorer for file management expose their users and administrators to these risks, especially in environments with multiple users or public-facing interfaces. The medium severity reflects the moderate ease of exploitation and limited scope of impact, but the risk increases if attackers combine this vulnerability with other flaws or social engineering tactics. Failure to patch could result in reputational damage, data leakage, and potential compliance violations for organizations handling sensitive information.

Summary

CVE-2025-13058 identifies a cross-site scripting vulnerability in soerennb eXtplorer, a web-based file management tool, affecting all versions up to 2.1.15. The vulnerability resides in an unspecified function of the Filename Handler component, which improperly sanitizes or validates input, allowing attackers to inject malicious JavaScript code. This XSS flaw can be exploited remotely without authentication but requires some user interaction, such as tricking a user into clicking a crafted link or visiting a malicious page. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no privileges required, user interaction needed, and limited impact on confidentiality and integrity, with no impact on availability. Successful exploitation could allow attackers to execute scripts in the victim’s browser, potentially leading to session hijacking, defacement, or redirection to malicious sites. Although no known exploits are currently reported in the wild, the vulnerability poses a risk to organizations using eXtplorer for file management on web servers. A patch identified by commit 002def70b985f7012586df2c44368845bf405ab3 has been released and should be applied to remediate the issue. The vulnerability highlights the importance of robust input validation and output encoding in web applications handling user-supplied data, especially in components managing filenames or file metadata.
