CVE-2025-5511: Improper Authorization in quequnlong shiyi-blog
A vulnerability, which was classified as critical, has been found in quequnlong shiyi-blog up to 1.2.1. This issue affects some unknown processing of the file /dev api/app/album/photos/. The manipulation leads to improper authorization. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
AI Analysis
Technical Summary
CVE-2025-5511 is a medium-severity vulnerability classified as an improper authorization flaw found in the quequnlong shiyi-blog software versions up to 1.2.1. The vulnerability specifically affects the processing of requests to the endpoint /dev api/app/album/photos/, where the application fails to correctly enforce authorization checks. This improper authorization allows an unauthenticated remote attacker to access or manipulate resources that should be restricted, potentially exposing sensitive data or enabling unauthorized actions within the photo album functionality of the blog platform. The vulnerability does not require any user interaction, privileges, or authentication, and can be exploited remotely over the network, increasing its risk profile. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N) indicates network attack vector, low attack complexity, no privileges or user interaction required, and limited impact on confidentiality only. The vendor has not responded to the vulnerability disclosure, and no patches or mitigations have been officially released. Although the exploit has been publicly disclosed, there are no known exploits actively used in the wild at this time. The vulnerability primarily impacts the integrity of authorization controls, potentially allowing unauthorized data access or modification within the affected endpoint. Given the nature of the flaw, attackers could leverage it to bypass access controls on photo album resources, which may lead to data leakage or unauthorized content manipulation within the shiyi-blog platform.
Potential Impact
For European organizations using the quequnlong shiyi-blog platform, this vulnerability poses a risk of unauthorized access to sensitive user-generated content or internal resources managed through the photo album feature. This could lead to exposure of private images or data, undermining user privacy and potentially violating data protection regulations such as the GDPR. The improper authorization flaw could also be exploited to alter or delete content, damaging the integrity and trustworthiness of the affected blogs. Organizations relying on shiyi-blog for public-facing or internal communications may face reputational damage and operational disruption if attackers exploit this vulnerability. Since the vulnerability can be exploited remotely without authentication, it increases the attack surface and risk of automated scanning and exploitation attempts. The lack of vendor response and patches further exacerbates the risk, requiring organizations to implement compensating controls. The impact is particularly significant for entities handling sensitive or regulated data, including media companies, educational institutions, and government agencies in Europe that might use this blogging platform.
Mitigation Recommendations
Given the absence of official patches, European organizations should immediately audit their use of the shiyi-blog platform and restrict access to the vulnerable endpoint /dev api/app/album/photos/. Network-level controls such as web application firewalls (WAFs) should be configured to detect and block suspicious requests targeting this endpoint, especially those attempting unauthorized access patterns. Organizations should consider isolating or disabling the photo album feature if it is not critical to operations. Monitoring and logging access to the affected API path should be enhanced to detect potential exploitation attempts. Applying strict access control policies at the network perimeter and internal segmentation can reduce exposure. If possible, organizations should upgrade to a non-vulnerable version of the software once available or migrate to alternative blogging platforms with active security maintenance. Additionally, organizations should conduct security awareness training for administrators to recognize signs of exploitation and establish incident response procedures tailored to this vulnerability. Regular vulnerability scanning and penetration testing focused on authorization controls are recommended to identify similar weaknesses proactively.
