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: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
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 on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 10 Jun 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

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.

What to do

AI-suggested

Immediate upgrade to GeoServer version 2.25.0 or later, which implements a secure ENTITY_RESOLUTION_ALLOWLIST by default, effectively mitigating this vulnerability.
If upgrading is not immediately feasible, disable XML external entity processing or configure GeoServer to use a strict entity resolution allowlist manually.
Implement network-level controls such as firewall rules or web application firewalls (WAFs) to restrict outbound HTTP requests from GeoServer servers to only trusted destinations, preventing abuse for internal network scanning.
Monitor GeoServer logs for unusual XML requests or outbound HTTP connections that could indicate exploitation attempts.
Conduct internal network segmentation to limit the exposure of sensitive internal services from servers exposed to external networks.
Review and harden XML processing configurations in GeoServer and related GeoTools libraries to ensure no other unsafe entity resolution mechanisms are enabled.
Educate administrators and developers about the risks of XXE and SSRF to prevent similar issues in custom extensions or integrations.

Description

GeoServer is an open source server that allows users to share and edit geospatial data. An improper URI validation vulnerability exists that enables an unauthorized attacker to perform XML External Entities (XEE) attack, then send GET request to any HTTP server. By default, GeoServer use PreventLocalEntityResolver class from GeoTools to filter out malicious URIs in XML entities before resolving them. The URI must match the regex (?i)(jar:file|http|vfs)[^?#;]*\\.xsd. But the regex leaves a chance for attackers to request to any HTTP server or limited file. Attacker can abuse this to scan internal networks and gain information about them then exploit further. GeoServer 2.25.0 and greater default to the use of ENTITY_RESOLUTION_ALLOWLIST and does not require you to provide a system property.

Impact

For European organizations, the impact of CVE-2024-34711 can be substantial, especially for those relying on GeoServer for managing sensitive geospatial data related to infrastructure, urban planning, environmental monitoring, or defense. The vulnerability enables attackers to perform internal network reconnaissance by abusing the server's XML entity resolution process to send arbitrary HTTP requests. This can expose internal IP addresses, services, and configurations that are typically shielded from external access, facilitating subsequent targeted attacks such as lateral movement, data exfiltration, or further exploitation of internal systems. Confidentiality is severely impacted as sensitive internal network information can be leaked. Integrity impact is moderate since the attacker can influence some server behavior via crafted XML but cannot directly modify data. Availability is not affected. Given the criticality and ease of exploitation without authentication, attackers can leverage this vulnerability to gain a foothold or gather intelligence for more damaging attacks. European public sector entities, utilities, transportation agencies, and private companies using GeoServer for critical geospatial services are particularly at risk. The exposure of internal network details could also contravene GDPR requirements regarding data protection and network security, leading to regulatory and reputational consequences.
