CVE-2026-2682 identifies a SQL injection vulnerability in the Tsinghua Unigroup Electronic Archives System, specifically affecting version 3.2.210802(62532). The vulnerability resides in an unspecified function accessed via the URL path /mine/PublicReport/prinReport.html, where the 'comid' parameter is improperly sanitized. This allows an attacker to inject crafted SQL statements remotely, without requiring authentication or user interaction, potentially manipulating backend database queries. The injection could lead to unauthorized data access, modification, or deletion, impacting confidentiality, integrity, and availability of archived electronic records. The vendor was notified but has not issued a patch or response, increasing the risk of exploitation once public details are widely known. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:L), no user interaction (UI:N), and low impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). No known exploits are currently reported in the wild, but public disclosure raises the likelihood of future attacks. The lack of patch links suggests organizations must rely on mitigations until an official fix is released.

For European organizations using the Tsinghua Unigroup Electronic Archives System, this vulnerability poses a risk of unauthorized access to sensitive archived data, potentially including personal, financial, or operational records. Exploitation could lead to data breaches, data manipulation, or denial of service conditions affecting business continuity. Given the system's role in managing electronic archives, integrity and availability impacts could disrupt regulatory compliance and operational processes. The medium severity rating reflects partial impact on confidentiality, integrity, and availability, but the absence of required authentication and user interaction increases exploitation feasibility. Organizations in sectors such as government, finance, healthcare, and critical infrastructure that rely on electronic archiving may face elevated risks. Additionally, the vendor's lack of response delays remediation, increasing exposure time. The threat could also facilitate lateral movement or further attacks if attackers gain footholds via this vulnerability.

European organizations should implement immediate mitigations including: 1) Deploying Web Application Firewalls (WAFs) with rules to detect and block SQL injection attempts targeting the 'comid' parameter or the affected URL path. 2) Applying strict input validation and sanitization on all user-supplied parameters, especially 'comid', to prevent injection of malicious SQL code. 3) Monitoring database logs and application logs for anomalous queries or error messages indicative of injection attempts. 4) Restricting database user privileges to the minimum necessary to limit potential damage from injection attacks. 5) Segmenting the network to isolate the archives system and reduce attack surface. 6) Preparing incident response plans specific to potential data breaches or service disruptions from this vulnerability. 7) Engaging with the vendor or community for updates or unofficial patches. 8) Considering alternative archival solutions if timely patching is not feasible. These steps go beyond generic advice by focusing on the specific injection vector and operational context of the archives system.
