CVE-2025-8815: Morning-pro Morning Path Traversal Flaw

CVE-2025-8815 Overview

CVE-2025-8815 is a path traversal vulnerability [CWE-22] in the Morning application from morning-pro. The flaw resides in the Shiro Configuration component, specifically in handling of the /index endpoint. Attackers can manipulate request input to traverse directories and access resources outside the intended scope. The vulnerability is exploitable remotely without authentication or user interaction. The exploit details have been publicly disclosed. Because Morning uses a rolling release model, no discrete affected or fixed version identifiers are available; the issue is tracked against commit bc782730c74ff080494f145cc363a0b4f43f7d3e and earlier.

Critical Impact
Unauthenticated remote attackers can perform path traversal against /index, potentially exposing sensitive files protected by the Shiro authorization layer.

Technical Details for CVE-2025-8815

Vulnerability Analysis

The vulnerability is a path traversal flaw [CWE-22] in the Shiro Configuration component of Morning. Apache Shiro is a Java security framework used for authentication, authorization, and session management. When Shiro path-matching patterns are configured improperly, attackers can craft request URIs that bypass authorization filters and access protected resources. In Morning, the /index endpoint processes request paths in a way that permits traversal sequences. An unauthenticated remote attacker can submit a crafted HTTP request to read content the Shiro filter chain was intended to gate. The public disclosure of exploit details raises the practical risk of opportunistic scanning and abuse.

Root Cause

The root cause is inconsistent URL normalization between the Shiro filter chain and the underlying servlet container. Shiro evaluates ant-style path patterns to decide whether a request requires authentication, while the application server resolves the actual resource using a different normalization routine. When traversal characters or encoded variants are introduced into the path, Shiro may classify the request as a public asset while the container serves a protected resource. The application does not sanitize or canonicalize the input path before authorization decisions are made.

Attack Vector

The attack vector is network-based and requires no authentication or user interaction. An attacker sends a single HTTP request to the /index endpoint containing crafted path segments. The Shiro Configuration mismatch causes the filter to grant access, after which the servlet container resolves the manipulated path against the file system or routing table. Successful exploitation discloses limited confidentiality, integrity, and availability impact according to the published CVSS vector. See the Gitee Issue ICOVAK Reporting and VulDB #319344 for technical details.

Detection Methods for CVE-2025-8815

Indicators of Compromise

HTTP requests to /index containing traversal sequences such as ../, ..\, %2e%2e%2f, or ; semicolon path parameters used to confuse Shiro pattern matching.
Requests producing unexpected 200 responses for endpoints normally protected by authentication.
Repeated probing from a single source IP targeting variations of /index paths.

Detection Strategies

Inspect web server and application access logs for request URIs containing encoded or doubled traversal tokens against the /index route.
Compare Shiro filter chain decisions against actual resolved resource paths to flag normalization mismatches.
Apply web application firewall signatures for known Shiro authorization bypass and path traversal patterns.

Monitoring Recommendations

Enable verbose Shiro filter logging temporarily to capture path-matching decisions during high-risk windows.
Alert on anomalous spikes in 200-response rates from previously low-traffic protected endpoints.
Correlate web access logs with file system audit logs to identify unauthorized resource retrieval.

How to Mitigate CVE-2025-8815

Immediate Actions Required

Update Morning to the latest rolling release commit beyond bc782730c74ff080494f145cc363a0b4f43f7d3e from the project repository.
Restrict public network exposure of the /index endpoint until the patched commit is deployed.
Audit Shiro configuration to ensure path patterns cover all variants and that wildcard rules do not permit traversal.

Patch Information

Morning is delivered as a rolling release, so no fixed version number is published. Administrators should pull the latest commit from the upstream Gitee repository and verify that the Shiro Configuration includes canonical path handling. Track upstream issue tracker activity at the Gitee Issue ICOVAK Reporting entry for fix confirmation.

Workarounds

Place a reverse proxy or web application firewall in front of Morning to normalize and reject request paths containing .., encoded traversal sequences, or trailing semicolons.
Tighten Shiro filter chain definitions so that protected paths use explicit patterns rather than broad wildcards.
Run the application under a low-privilege OS account with read access limited to required directories to reduce the impact of successful traversal.

bash

# Example nginx reject rule for traversal patterns reaching /index
location /index {
    if ($request_uri ~* "(\.\./|\.\.\\|%2e%2e%2f|%2e%2e/|/%2e%2e)") {
        return 400;
    }
    proxy_pass http://morning_backend;
