CVE-2022-1373 in Secure Integration Server
Summary
by MITRE • 08/18/2022
The “restore configuration” feature of Softing Secure Integration Server V1.22 is vulnerable to a directory traversal vulnerability when processing zip files. An attacker can craft a zip file to load an arbitrary dll and execute code. Using the "restore configuration" feature to upload a zip file containing a path traversal file may cause a file to be created and executed upon touching the disk.

The vulnerability identified as CVE-2022-1373 resides within the Softing Secure Integration Server V1.22 software, specifically targeting its configuration restoration functionality. This issue represents a critical directory traversal flaw that fundamentally compromises the system's integrity by allowing unauthorized code execution through seemingly benign file upload operations. The vulnerability manifests when the application processes zip archives during the restore configuration workflow, creating an attack surface where malicious actors can manipulate file paths to execute arbitrary code on the target system.
The technical exploitation of this vulnerability follows a directory traversal pattern that enables attackers to manipulate the file extraction process within zip archives. When a user uploads a specially crafted zip file through the restore configuration feature, the application fails to properly validate or sanitize the file paths contained within the archive. This validation gap allows attackers to include malicious dll files with paths that traverse outside the intended directory structure, potentially placing executable code in system directories or other critical locations where it can be executed upon system interaction. The vulnerability directly maps to CWE-22, which describes improper limitation of a pathname to a restricted directory, commonly known as path traversal or directory traversal attacks.
The operational impact of this vulnerability extends beyond simple code execution, as it provides attackers with persistent access to the affected system. Once successfully exploited, the malicious dll files can establish backdoors, escalate privileges, or perform additional malicious activities within the network environment. The attack vector is particularly concerning because it leverages legitimate administrative functions, making it harder to detect through standard security monitoring. The vulnerability's exploitation requires minimal privileges and can be automated, potentially enabling large-scale attacks against systems running the affected software version. This weakness creates a persistent threat that can be used for data exfiltration, lateral movement, or establishment of persistent command and control channels.
Organizations utilizing Softing Secure Integration Server V1.22 should immediately implement mitigations to address this vulnerability. The primary recommendation involves applying the vendor's official patch or upgrade to a version that resolves the directory traversal issue. Until a permanent fix is deployed, administrators should restrict access to the restore configuration feature and implement strict file validation for all uploaded zip archives. Network segmentation and monitoring of file upload activities can help detect potential exploitation attempts. The vulnerability also highlights the importance of input validation and proper file path handling in software development practices, aligning with ATT&CK technique T1059.001 for command and script injection and T1566.001 for spearphishing attachments. Security teams should conduct comprehensive vulnerability assessments to identify other systems potentially affected by similar path traversal issues, as this class of vulnerability remains prevalent in enterprise software environments and represents a common target for advanced persistent threat actors.
