A critical vulnerability, CVE-2023-4740, has been identified in IBOS OA 4.5.5, which is an Office Automation platform typically used by businesses to streamline their daily operations. This security flaw exposes the system to an SQL injection attack, specifically targeting the Delete Draft Handler component, and allows attackers to potentially gain unauthorized access to sensitive information. Sadly, despite multiple attempts, the vendor has failed to respond to our disclosure or offer any solutions to mitigate the issue. As a result, necessary steps must be taken by affected users to protect themselves until a patch can be released by the vendor.
The vulnerability affects a file with an unknown part, "?r=email/api/delDraft&archiveId=" of the Delete Draft Handler component. Attackers can leverage this security flaw by initiating a manipulated SQL query to bypass authentication or retrieve and delete data. Since it can be initiated remotely, this increases the risk associated with this vulnerability.
Initiating the attack remotely with a malicious link or script.
2. The malicious query targets the Delete Draft Handler component by exploiting the "?r=email/api/delDraft&archiveId=" file.
3. Injecting the SQL query to manipulate or delete data, gain unauthorized access, or perform unauthorized actions in the IBOS OA system.
Vulnerability Database (VDB) Identifier
The Vulnerability Database (VDB) has assigned the identifier VDB-238629 to this vulnerability due to its severity and the potential risk it poses to affected users.
