CVE-2020-35674
CWE-89Published: September 29, 2022· Updated: Jun 17, 2026
Official Description
BigProf Online Invoicing System before 2.9 suffers from an unauthenticated SQL Injection found in /membership_passwordReset.php (the endpoint that is responsible for issuing self-service password resets). An unauthenticated attacker is able to send a request containing a crafted payload that can result in sensitive information being extracted from the database, eventually leading into an application takeover. This vulnerability was introduced as a result of the developer trying to roll their own sanitization implementation in order to allow the application to be used in legacy environments.
Risk Analysis
The BigProf Online Invoicing System contains an unauthenticated SQL injection vulnerability in the password reset endpoint. This allows attackers to extract sensitive database information and potentially take over the application. The critical severity reflects the ease of exploitation and the impact on system security.
No public exploit is known, and it is not in the CISA KEV. The vulnerability is remotely exploitable with low attack complexity.
Upgrade to version 2.9 or later to receive the necessary security fixes.
Technical Analysis
CVE-2020-35674 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
From a weakness classification perspective (CWE-89): SQL injection vulnerabilities allow attackers to manipulate database queries, potentially exposing or modifying sensitive data.
