Description
This security bulletin contains information about 16 secuirty vulnerabilities.
1) 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.
2) Use-after-free (CVE-ID: CVE-2024-4741)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error within the SSL_free_buffers() function. A remote attacker can trigger a use-after-free error and perform a denial of service (DoS) attack.
Note, the vulnerability affects only applications that call the vulnerable function.
3) 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.
4) 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.
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-2024-38475)
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.
7) 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.
8) 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.
9) Command Injection (CVE-ID: CVE-2024-36138)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to improper handling of batch files in child_process.spawn / child_process.spawnSync on Windows. An attacker can inject a malicious command line argument and achieve code execution even if the shell option is not enabled.
Note, the vulnerability exists due to incomplete fix for #VU88462 (CVE-2024-27980).
10) NULL pointer dereference (CVE-ID: CVE-2024-36387)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error when handling websocket over HTTP/2 connections. A remote attacker can send specially crafted data to the web server and perform a denial of service (DoS) attack.
11) Information disclosure (CVE-ID: CVE-2024-39884)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to an error when processing legacy content-type based configuration of handlers, such as "AddType" and similar configuration when files are requested indirectly. A remote attacker can send a specially crafted HTTP request and view contents of files, for example the source code of a PHP script can be served instead of interpreted.
12) Input validation error (CVE-ID: CVE-2024-37372)
The vulnerability allows a remote user to bypass permissions model.
The vulnerability exists due to insufficient validation of UNC paths with backslashes. A remote user can bypass certain security restrictions.
13) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2024-36137)
The vulnerability allows a remote user to escalate privileges within the application.
The vulnerability exists due to application does not properly impose security restrictions in the experimental permission model when the --allow-fs-write flag is used. A remote user can change file ownership and permissions via fs.fchown and fs.fchmod.
14) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2024-22018)
The vulnerability allows a remote user to bypass permissions model.
The vulnerability exists due to application does not properly impose security restrictions when experimental permission model when the --allow-fs-read flag is used. A remote user can retrieve stats from files that they do not have explicit read access to.
15) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2024-22020)
The disclosed vulnerability allows a remote user to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input when handling non-network imports in data URLs. A remote user can bypass network import restrictions and execute arbitrary code.
16) Command Injection (CVE-ID: CVE-2024-27980)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to improper handling of batch files in child_process.spawn / child_process.spawnSync. An attacker can inject a malicious command line argument and achieve code execution even if the shell option is not enabled.
