Summary

CVE-2024-55507 is a critical-severity Improper Preservation of Permissions (CWE-281) vulnerability in Codeastro Complaint Management System. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 34.5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 AC-3 (Access Enforcement) and SI-2 (Flaw Remediation).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploitation for Privilege Escalation (T1068) and 1 other technique. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

AC-3 Access Enforcement good match

prevent

Enforces approved access authorizations to directly prevent unauthorized privilege escalation via the flawed delete_e.php component.

AC-6 Least Privilege partial match

prevent

Applies least privilege to restrict excessive access rights, mitigating the impact of privilege escalation even if enforcement partially fails.

SI-2 Flaw Remediation good match

prevent

Identifies, reports, and corrects software flaws like the improper permission handling in delete_e.php that enables remote privilege escalation.

MITRE ATT&CK Enterprise TechniquesAI

T1068 Exploitation for Privilege Escalation Privilege Escalation

Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.

Why these techniques?

CVE-2024-55507 enables remote privilege escalation via a web application component (delete_e.php), facilitating T1068 (Exploitation for Privilege Escalation) and T1190 (Exploit Public-Facing Application).

NVD Description

An issue in CodeAstro Complaint Management System v.1.0 allows a remote attacker to escalate privileges via the delete_e.php component.

Deeper analysisAI

CVE-2024-55507 is a privilege escalation vulnerability affecting CodeAstro Complaint Management System version 1.0. The flaw exists in the delete_e.php component, where improper handling allows unauthorized privilege elevation. It carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) and is associated with CWE-281.

A remote attacker requires only network access, low attack complexity, no prior privileges, and no user interaction to exploit the vulnerability. Successful exploitation enables high-impact compromise of confidentiality, integrity, and availability, allowing the attacker to escalate privileges on the affected system.
