CVE-2025-27274 is a path traversal vulnerability identified in the axelkeller GPX Viewer software, specifically affecting versions up to and including 2.2.11. The vulnerability arises from improper sanitization of file path inputs, allowing an attacker to exploit the '.../...//' sequence to navigate directories beyond the intended root directory. This can enable an attacker to access arbitrary files on the system where the GPX Viewer is running, potentially exposing sensitive information or configuration files. The vulnerability is particularly concerning because GPX Viewer is used to visualize GPS data, often in contexts involving geographic information systems (GIS), outdoor navigation, and logistics. Although no exploits have been reported in the wild, the flaw could be leveraged by an attacker who can trick a user into opening a maliciously crafted GPX file containing the traversal payload. The vulnerability does not require authentication, increasing its risk profile. The lack of a CVSS score suggests it is newly disclosed, but the technical details indicate a significant security gap. The vendor has not yet released a patch, and no mitigation links are currently available. The vulnerability was reserved and published in early 2025, indicating recent discovery and disclosure.

The primary impact of CVE-2025-27274 is unauthorized access to files outside the intended directory scope of the GPX Viewer application. This can lead to exposure of sensitive data such as configuration files, credentials, or other private information stored on the host system. For organizations relying on GPX Viewer for critical operations, this could compromise operational security and privacy. Additionally, attackers could use the vulnerability as a foothold to further escalate privileges or move laterally within a network if the application runs with elevated permissions. The lack of authentication requirements and the possibility of exploitation through user interaction (opening a crafted GPX file) increase the attack surface. While no active exploits are known, the vulnerability could be weaponized in targeted attacks against organizations in sectors like transportation, logistics, defense, and geographic data analysis. The global nature of GPX Viewer usage means that the threat is not geographically limited, but organizations with high reliance on GPS data visualization tools are particularly at risk.

1. Monitor for official patches or updates from axelkeller and apply them immediately once available. 2. Until a patch is released, implement strict input validation and sanitization on all GPX files before opening them in GPX Viewer, rejecting files containing suspicious path traversal sequences like '.../...//'. 3. Run GPX Viewer with the least privileges possible, ideally in a sandboxed or containerized environment to limit filesystem access. 4. Educate users to avoid opening GPX files from untrusted or unknown sources. 5. Employ endpoint security solutions capable of detecting anomalous file access patterns or exploitation attempts related to path traversal. 6. Consider network-level controls to restrict GPX Viewer usage to trusted environments. 7. Review and harden file system permissions to minimize the impact of unauthorized file access. 8. Maintain comprehensive logging and monitoring to detect any attempts to exploit this vulnerability.
