Attack Vector: Network

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the Vulnerable System.
Vulnerable system integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact to the Vulnerable System.
Vulnerable system availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the Vulnerable System are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

Exploitation evidence

Detectable: no evidence on record.

Exploited in the wildExploited: no evidence on record.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

AI-suggested

European organizations should immediately audit their use of the chaitak-gorai Blogbook platform and restrict access to the /admin/view_all_posts.php endpoint through network-level controls such as IP whitelisting or VPN access. Implementing Web Application Firewalls (WAF) with SQL Injection detection and prevention rules can help block malicious payloads targeting the 'post_id' parameter. Regularly monitoring logs for suspicious query patterns and anomalous database activity is critical. Additionally, organizations should isolate the Blogbook administrative interface from public networks where possible and enforce strong authentication and authorization policies to minimize exposure.

Description

A vulnerability classified as critical has been found in chaitak-gorai Blogbook up to 92f5cf90f8a7e6566b576fe0952e14e1c6736513. This affects an unknown part of the file /admin/view_all_posts.php of the component GET Parameter Handler. The manipulation of the argument post_id leads to sql injection. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. This product does not use versioning. This is why information about affected and unaffected releases are unavailable. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

For European organizations using the chaitak-gorai Blogbook platform, this vulnerability poses a risk of unauthorized database access or manipulation, which could lead to data breaches, defacement of blog content, or disruption of administrative functions. Given the administrative context of the affected endpoint, attackers could potentially extract sensitive post data or modify content, impacting the integrity and confidentiality of organizational information. Although the severity is medium, the lack of vendor response and patch availability increases exposure duration. Organizations in sectors with strict data protection regulations, such as GDPR, may face compliance risks if sensitive personal data is compromised. The remote exploitability without authentication heightens the threat, especially for organizations with exposed administrative interfaces. However, the limited impact on availability reduces the likelihood of widespread service disruption.

Summary

CVE-2025-5403 is a medium-severity SQL Injection vulnerability identified in the chaitak-gorai Blogbook product, specifically affecting the /admin/view_all_posts.php file within the GET parameter handler component. The vulnerability arises from improper sanitization or validation of the 'post_id' parameter, allowing an attacker to inject malicious SQL code remotely without requiring user interaction or authentication. This can lead to unauthorized access or manipulation of the backend database, potentially exposing sensitive information or altering data integrity. The CVSS 4.0 base score is 5.3, reflecting a medium severity level, with an attack vector of network (remote), low attack complexity, no privileges required, and no user interaction needed. The impact on confidentiality, integrity, and availability is low to limited, suggesting that while exploitation is feasible, the scope of damage may be contained. No known exploits are currently reported in the wild, but the public disclosure increases the risk of exploitation attempts.
