The vulnerability identified as CVE-2025-70084 affects OpenSatKit version 2.2.1, specifically within the FileUtil_GetFileInfo function. This function improperly sanitizes input, allowing attackers to perform directory traversal attacks by crafting malicious input values. Directory traversal (CWE-22) enables attackers to navigate outside the intended directory structure and access arbitrary files on the system. In this case, attackers can read sensitive files, potentially exposing confidential mission data or system configuration files. The vulnerability is exploitable remotely over the network without requiring authentication or user interaction, increasing its risk profile. The CVSS 3.1 base score is 7.5 (high), reflecting the ease of exploitation (low attack complexity), no privileges required, and a significant confidentiality impact. However, the vulnerability does not affect integrity or availability, limiting the scope of damage to information disclosure. No patches or mitigations have been officially released at the time of publication, and no active exploitation has been reported. The vulnerability's presence in OpenSatKit, a software toolkit used for satellite mission operations and space systems, raises concerns about the confidentiality of sensitive aerospace data and operational security.

The primary impact of CVE-2025-70084 is unauthorized disclosure of sensitive information stored on systems running OpenSatKit 2.2.1. Attackers exploiting this vulnerability can access files outside the intended directory scope, potentially exposing mission-critical data, system credentials, or configuration files. This breach of confidentiality could lead to further targeted attacks, espionage, or operational disruptions in aerospace and satellite operations. While the vulnerability does not directly affect system integrity or availability, the exposure of sensitive information can undermine trust, cause regulatory compliance issues, and lead to reputational damage. Organizations worldwide using OpenSatKit in aerospace, defense, or research sectors are at risk, especially those with network-exposed instances of the vulnerable software. The lack of authentication requirements and ease of exploitation increase the urgency for mitigation. Although no known exploits are currently active, the vulnerability represents a significant risk if weaponized by threat actors.

Given the absence of official patches, organizations should implement immediate compensating controls to mitigate CVE-2025-70084. First, apply strict input validation and sanitization on all inputs to the FileUtil_GetFileInfo function to prevent directory traversal sequences such as '../'. Employ allowlisting of acceptable file paths and reject any input containing path traversal characters or patterns. Restrict file system permissions to limit access to sensitive directories and files, ensuring the OpenSatKit process runs with the least privileges necessary. Network-level controls such as firewalls and intrusion detection/prevention systems should monitor and block suspicious requests targeting file information functions. Conduct thorough logging and monitoring of file access attempts to detect potential exploitation attempts early. Organizations should also engage with the OpenSatKit community or vendor to obtain patches or updates as soon as they become available. Finally, consider isolating vulnerable instances from public networks or restricting access to trusted users only until a permanent fix is deployed.
