SB2024082016 - Multiple vulnerabilities in IBM Business Automation Workflow

Description

This security bulletin contains information about 7 secuirty vulnerabilities.

1) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2024-38472)

The disclosed vulnerability allows a remote attacker to perform SSRF attacks.

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can send a specially crafted HTTP request and trick the web server to leak NTLM hashes.

Note, the vulnerability affects Windows installations only.

2) Input validation error (CVE-ID: CVE-2024-38473)

The vulnerability allows a remote attacker to bypass authentication.

The vulnerability exists due to insufficient validation of user-supplied input when handling incorrect encoding in mod_proxy. A remote attacker can force the web server to pass request URLs with incorrect encoding to backend services.

3) Input validation error (CVE-ID: CVE-2024-38474)

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to insufficient validation of user-supplied input in mod_rewrite when parsing encoded question marks in backreferences. A remote attacker can execute scripts in directories permitted by the configuration but not directly reachable by any URL or source disclosure of scripts meant to only to be executed as CGI.

4) Input validation error (CVE-ID: CVE-2024-38475)

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to insufficient validation of user-supplied input in mod_rewrite when first segment of substitution matches filesystem path. A remote attacker can map URLs to filesystem locations that are permitted to be served by the server but are not intentionally/directly reachable by any URL and view contents of files or execute arbitrary code.

5) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2024-38476)

The disclosed vulnerability allows a remote attacker to perform SSRF attacks.

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker with control over the backend server can run local handlers via internal redirect and gain access to sensitive information or compromise the affected system.

6) Input validation error (CVE-ID: CVE-2024-38477)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input in mod_proxy. A remote attacker can send specially crafted requests to the web server and perform a denial of service (DoS) attack.

7) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2024-39573)

The disclosed vulnerability allows a remote attacker to perform SSRF attacks.

The vulnerability exists due to insufficient validation of user-supplied input in mod_rewrite proxy handler substitution. A remote attacker can cause unsafe RewriteRules to unexpectedly setup URL's to be handled by mod_proxy.
