CVE-2026-4321: SQLi in Raera's Destekz

Synopsis

SQL injection vulnerability in Raera Destekz allows a remote, unauthenticated attacker to send crafted SQL commands to the application over the network. No login or user interaction is required to trigger the flaw. Successful exploitation gives the attacker full read, write, and denial-of-service access to the underlying database. HarborGuard tracks this advisory for patch availability; no upstream fix has been published and the vendor has confirmed the product is unsupported.

HarborGuard Coverage

Exploit Conditions

• Network reachabilityRequired

  The attacker must be able to reach the Destekz service over the network; the vulnerability is remotely exploitable with no physical or local access needed.

• AuthenticationNot required

  No account or session credential of any privilege level is needed to send malicious SQL payloads.

• Victim interactionNot required

  The attacker acts entirely on their own; no user needs to click a link, open a file, or take any other action for the exploit to succeed.

• Attack complexityDetail

  The exploit is reliable and condition-free, requiring no race conditions, specific memory layout, or environmental setup beyond network access.

Blast Radius

• Reads the full contents of the application database, including stored credentials, session tokens, and any customer records held by Destekz.
• Modifies or deletes persisted database rows, enabling data tampering, account takeover, or destruction of application state.
• Crashes or degrades the database service, causing a denial of service for the application and its users.
• With write access to the database, an attacker may be able to inject stored payloads that affect subsequent application behavior.
