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

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, 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: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

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

Given the absence of an official patch, European organizations should implement the following specific mitigations: 1) Restrict network access to the Femitter Server by applying firewall rules to limit connections only to trusted IP addresses and internal networks. 2) Employ web application firewalls (WAFs) or intrusion prevention systems (IPS) to detect and block path traversal attack patterns targeting the server. 3) Conduct thorough input validation and sanitization on any user-supplied data if customization or scripting is possible within the server environment. 4) Monitor server logs for unusual file access patterns or suspicious requests that may indicate exploitation attempts. 5) Isolate the Femitter Server in a segmented network zone to minimize lateral movement if compromised. 6) If feasible, replace or upgrade the Femitter Server to a more secure alternative or newer version once available. 7) Educate users about the risks of interacting with untrusted or suspicious content related to the server to reduce the likelihood of user interaction exploitation. These measures go beyond generic advice by focusing on network-level controls, monitoring, and user awareness tailored to the Femitter Server context.

Description

A vulnerability, which was classified as problematic, was found in Acritum Femitter Server 1.04. Affected is an unknown function. The manipulation leads to path traversal. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. VDB-250446 is the identifier assigned to this vulnerability.

Impact

For European organizations using Acritum Femitter Server 1.04, this vulnerability poses a risk of unauthorized disclosure of sensitive information stored on the server. Confidential data such as configuration files, credentials, or business-critical documents could be exposed, potentially leading to further compromise or data breaches. Since the vulnerability does not affect integrity or availability directly, the immediate risk is limited to information disclosure. However, attackers could leverage the disclosed information to escalate attacks or gain deeper access. Organizations in sectors with strict data protection regulations, such as finance, healthcare, or government, could face compliance issues and reputational damage if sensitive data is leaked. The remote exploitability without authentication increases the attack surface, especially if the Femitter Server is exposed to the internet or untrusted networks. The requirement for user interaction might limit automated exploitation but does not eliminate risk, particularly in environments where users interact with the server regularly.

Summary

CVE-2010-10011 is a path traversal vulnerability identified in Acritum Femitter Server version 1.04. The vulnerability stems from improper validation of user-supplied input in an unspecified function within the server software, allowing an attacker to manipulate file paths. This manipulation enables the attacker to traverse directories outside the intended file system boundaries, potentially accessing sensitive files on the server. The vulnerability is remotely exploitable without requiring authentication, but it does require user interaction, such as sending a crafted request to the server. The CVSS 3.1 base score is 4.3, indicating a medium severity level. The attack vector is network-based with low attack complexity and no privileges required, but user interaction is necessary. The impact primarily affects confidentiality, as the attacker can read files outside the intended directory, but there is no direct impact on integrity or availability. No known exploits are currently observed in the wild, and no patches have been published yet. The vulnerability was publicly disclosed in January 2024, and the exploit details are available, which could increase the risk of exploitation over time if unmitigated.

Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #6OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
Architecture and Design
For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks…
Implementation · Input Validation
Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174).
