VAR-202106-1921
Vulnerability from variot - Updated: 2026-03-09 22:17A security issue in nginx resolver was identified, which might allow an attacker who is able to forge UDP packets from the DNS server to cause 1-byte memory overwrite, resulting in worker process crash or potential other impact. Nginx is a lightweight web server/reverse proxy server and email (IMAP/POP3) proxy server of Nginx Company in the United States. Affected products and versions are as follows: nginx: 0.6.18, 0.6.19 0.6.20, 0.6.21, 0.6.22 0.6.23, 0.6.24, 0.6.25, 0.6.26, 0.6.27, 0.6. A flaw was found in nginx. An off-by-one error while processing DNS responses allows a network malicious user to write a dot character out of bounds in a heap allocated buffer which can allow overwriting the least significant byte of next heap chunk metadata likely leading to a remote code execution in certain circumstances. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2021-23017). -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512
Debian Security Advisory DSA-4921-1 security@debian.org https://www.debian.org/security/ Moritz Muehlenhoff May 28, 2021 https://www.debian.org/security/faq
Package : nginx CVE ID : CVE-2021-23017 Debian Bug : 989095
Luis Merino, Markus Vervier and Eric Sesterhenn discovered an off-by-one in Nginx, a high-performance web and reverse proxy server, which could result in denial of service and potentially the execution of arbitrary code.
For the stable distribution (buster), this problem has been fixed in version 1.14.2-2+deb10u4.
We recommend that you upgrade your nginx packages.

"data": "A security issue in nginx resolver was identified, which might allow an attacker who is able to forge UDP packets from the DNS server to cause 1-byte memory overwrite, resulting in worker process crash or potential other impact. Nginx is a lightweight web server/reverse proxy server and email (IMAP/POP3) proxy server of Nginx Company in the United States. Affected products and versions are as follows: nginx: 0.6.18, 0.6.19 0.6.20, 0.6.21, 0.6.22 0.6.23, 0.6.24, 0.6.25, 0.6.26, 0.6.27, 0.6. A flaw was found in nginx. An off-by-one error while processing DNS responses allows a network malicious user to write a dot character out of bounds in a heap allocated buffer which can allow overwriting the least significant byte of next heap chunk metadata likely leading to a remote code execution in certain circumstances. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

nginx vulnerability
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 22.04 LTS
Summary:
nginx could be made to redirect network traffic.
Software Description: - nginx: small, powerful, scalable web/proxy server
Details:
USN-5371-1 fixed several vulnerabilities in nginx. This update provides the fix for CVE-2021-3618 for Ubuntu 22.04 LTS.
Original advisory details:
It was discovered that nginx Lua module mishandled certain inputs. An attacker could possibly use this issue to perform an HTTP Request Smuggling attack. This issue only affects Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (CVE-2020-11724)
It was discovered that nginx Lua module mishandled certain inputs. An attacker could possibly use this issue to disclose sensitive information. This issue only affects Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (CVE-2020-36309)
It was discovered that nginx mishandled the use of compatible certificates among multiple encryption protocols. If a remote attacker were able to intercept the communication, this issue could be used to redirect traffic between subdomains. (CVE-2021-3618)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 22.04 LTS: nginx-core 1.18.0-6ubuntu14.1 nginx-extras 1.18.0-6ubuntu14.1 nginx-light 1.18.0-6ubuntu14.1

VAR-201804-1376
Vulnerability from variot - Updated: 2023-11-09 23:47In OpenResty through 1.13.6.1, URI parameters are obtained using the ngx.req.get_uri_args and ngx.req.get_post_args functions that ignore parameters beyond the hundredth one, which might allow remote attackers to bypass intended access restrictions or interfere with certain Web Application Firewall (ngx_lua_waf or X-WAF) products. NOTE: the vendor has reported that 100 parameters is an intentional default setting, but is adjustable within the API. The vendor's position is that a security-relevant misuse of the API by a WAF product is a vulnerability in the WAF product, not a vulnerability in OpenResty. ** Unsettled ** This case has not been confirmed as a vulnerability. OpenResty Is SQL An injection vulnerability exists. The vendor has disputed this vulnerability. For details, see NVD of Current Description Please Confirm. https://nvd.nist.gov/vuln/detail/CVE-2018-9230Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state

"data": "In OpenResty through 1.13.6.1, URI parameters are obtained using the ngx.req.get_uri_args and ngx.req.get_post_args functions that ignore parameters beyond the hundredth one, which might allow remote attackers to bypass intended access restrictions or interfere with certain Web Application Firewall (ngx_lua_waf or X-WAF) products. NOTE: the vendor has reported that 100 parameters is an intentional default setting, but is adjustable within the API. The vendor\u0027s position is that a security-relevant misuse of the API by a WAF product is a vulnerability in the WAF product, not a vulnerability in OpenResty. ** Unsettled ** This case has not been confirmed as a vulnerability. OpenResty Is SQL An injection vulnerability exists. The vendor has disputed this vulnerability.

CVE-2024-39702 (GCVE-0-2024-39702)
Vulnerability from nvd – Published: 2024-07-23 00:00 – Updated: 2024-11-26 17:58
VLAI?
Summary
In lj_str_hash.c in OpenResty 1.19.3.1 through 1.25.3.1, the string hashing function (used during string interning) allows HashDoS (Hash Denial of Service) attacks. An attacker could cause excessive resource usage during proxy operations via crafted requests, potentially leading to a denial of service with relatively few incoming requests. This vulnerability only exists in the OpenResty fork in the openresty/luajit2 GitHub repository. The LuaJIT/LuaJIT repository. is unaffected.

CVE-2018-9230 (GCVE-0-2018-9230)
Vulnerability from nvd – Published: 2018-04-02 18:00 – Updated: 2024-08-05 07:17 Disputed
VLAI?
Summary
In OpenResty through 1.13.6.1, URI parameters are obtained using the ngx.req.get_uri_args and ngx.req.get_post_args functions that ignore parameters beyond the hundredth one, which might allow remote attackers to bypass intended access restrictions or interfere with certain Web Application Firewall (ngx_lua_waf or X-WAF) products. NOTE: the vendor has reported that 100 parameters is an intentional default setting, but is adjustable within the API. The vendor's position is that a security-relevant misuse of the API by a WAF product is a vulnerability in the WAF product, not a vulnerability in OpenResty

CVE-2024-39702 (GCVE-0-2024-39702)
Vulnerability from cvelistv5 – Published: 2024-07-23 00:00 – Updated: 2024-11-26 17:58
VLAI?
Summary
In lj_str_hash.c in OpenResty 1.19.3.1 through 1.25.3.1, the string hashing function (used during string interning) allows HashDoS (Hash Denial of Service) attacks. An attacker could cause excessive resource usage during proxy operations via crafted requests, potentially leading to a denial of service with relatively few incoming requests. This vulnerability only exists in the OpenResty fork in the openresty/luajit2 GitHub repository. The LuaJIT/LuaJIT repository. is unaffected.

CVE-2018-9230 (GCVE-0-2018-9230)
Vulnerability from cvelistv5 – Published: 2018-04-02 18:00 – Updated: 2024-08-05 07:17 Disputed
VLAI?
Summary
In OpenResty through 1.13.6.1, URI parameters are obtained using the ngx.req.get_uri_args and ngx.req.get_post_args functions that ignore parameters beyond the hundredth one, which might allow remote attackers to bypass intended access restrictions or interfere with certain Web Application Firewall (ngx_lua_waf or X-WAF) products. NOTE: the vendor has reported that 100 parameters is an intentional default setting, but is adjustable within the API. The vendor's position is that a security-relevant misuse of the API by a WAF product is a vulnerability in the WAF product, not a vulnerability in OpenResty
