Successful exploitation of the vulnerability results in privilege escalation on the vulnerable system.

12) Integer overflow (CVE-ID: CVE-2017-7529)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to integer overflow when processing specially crafted requests. A remote attacker can send a malicious request to vulnerable server and gain access to potentially sensitive information.
 
When using nginx with standard modules this allows an attacker to obtain a cache file header if a response was returned from cache. In some configurations a cache file header may contain IP address of the backend server or other sensitive information.

13) Buffer over-read (CVE-ID: CVE-2018-16845)

The vulnerability allows a remote attacker to gain access to potentially sensitive information or trigger denial of service conditions.

The vulnerability exists due to a boundary condition when processing headers of MP4 files within the ngx_http_mp4_module module. A remote attacker can create a specially crafted MP4 file, trick the victim into uploading it on the server and trigger application crash or disclosure of the worker's process memory.

Successful exploitation of the vulnerability requires that nginx is compiled with support for ngx_http_mp4_module module (not a default configuration).


14) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2019-20372)

The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.

The vulnerability exists with certain error_page configurations. A remote attacker can read unauthorized web pages in environments where NGINX is being fronted by a load balancer.


15) Off-by-one (CVE-ID: CVE-2021-23017)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to an off-by-one error within the ngx_resolver_copy() function when processing DNS responses. A remote attacker can trigger an off-by-one error, write a dot character (‘.’, 0x2E) out of bounds in a heap allocated buffer and execute arbitrary code on the system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

The vulnerability can be triggered by a DNS response in reply to a DNS request from nginx when the resolver primitive is configured. A specially crafted packet allows overwriting the least significant byte of next heap chunk metadata with 0x2E.


16) Origin validation error (CVE-ID: CVE-2021-3618)

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to a logic error in TLS implementation when handling different protocols but using compatible certificates, such as multi-domain or wildcard certificates. A remote attacker with ability to perform TCP/IP layer MitM attack can redirect traffic from one subdomain to another, resulting in a valid TLS session.
