Debian Security Advisory DSA-5522-1 security@debian.org https://www.debian.org/security/ Markus Koschany October 10, 2023 https://www.debian.org/security/faq
Package : tomcat9 CVE ID : CVE-2023-24998 CVE-2023-41080 CVE-2023-42795 CVE-2023-44487 CVE-2023-45648
Several security vulnerabilities have been discovered in the Tomcat servlet and JSP engine.
CVE-2023-24998
Denial of service. Tomcat uses a packaged renamed copy of Apache Commons
FileUpload to provide the file upload functionality defined in the Jakarta
Servlet specification. Apache Tomcat was, therefore, also vulnerable to the
Commons FileUpload vulnerability CVE-2023-24998 as there was no limit to
the number of request parts processed. This resulted in the possibility of
an attacker triggering a DoS with a malicious upload or series of uploads.
CVE-2023-41080
Open redirect. If the ROOT (default) web application is configured to use
FORM authentication then it is possible that a specially crafted URL could
be used to trigger a redirect to an URL of the attackers choice.
CVE-2023-42795
Information Disclosure. When recycling various internal objects, including
the request and the response, prior to re-use by the next request/response,
an error could cause Tomcat to skip some parts of the recycling process
leading to information leaking from the current request/response to the
next.
CVE-2023-44487
DoS caused by HTTP/2 frame overhead (Rapid Reset Attack)
CVE-2023-45648
Request smuggling. Tomcat did not correctly parse HTTP trailer headers. A
specially crafted, invalid trailer header could cause Tomcat to treat a
single request as multiple requests leading to the possibility of request
smuggling when behind a reverse proxy.
For the oldstable distribution (bullseye), these problems have been fixed in version 9.0.43-2~deb11u7.
We recommend that you upgrade your tomcat9 packages.
For the detailed security status of tomcat9 please refer to its security tracker page at: https://security-tracker.debian.org/tracker/tomcat9

Tomcat uses a packaged renamed copy of Apache Commons\n FileUpload to provide the file upload functionality defined in the Jakarta\n Servlet specification. Apache Tomcat was, therefore, also vulnerable to the\n Commons FileUpload vulnerability CVE-2023-24998 as there was no limit to\n the number of request parts processed. This resulted in the possibility of\n an attacker triggering a DoS with a malicious upload or series of uploads. \n\nCVE-2023-41080\n\n Open redirect. If the ROOT (default) web application is configured to use\n FORM authentication then it is possible that a specially crafted URL could\n be used to trigger a redirect to an URL of the attackers choice. \n\nCVE-2023-42795\n\n Information Disclosure. When recycling various internal objects, including\n the request and the response, prior to re-use by the next request/response,\n an error could cause Tomcat to skip some parts of the recycling process\n leading to information leaking from the current request/response to the\n next. \n\nCVE-2023-44487\n\n DoS caused by HTTP/2 frame overhead (Rapid Reset Attack)\n\nCVE-2023-45648\n\n Request smuggling. Tomcat did not correctly parse HTTP trailer headers. A\n specially crafted, invalid trailer header could cause Tomcat to treat a\n single request as multiple requests leading to the possibility of request\n smuggling when behind a reverse proxy. \n\nFor the oldstable distribution (bullseye), these problems have been fixed\nin version 9.0.43-2~deb11u7. \n\nWe recommend that you upgrade your tomcat9 packages. \n\nFor the detailed security status of tomcat9 please refer to\nits security tracker page at:\nhttps://security-tracker.debian.org/tracker/tomcat9\n\nFurther information about Debian Security Advisories, how to apply\nthese updates to your system and frequently asked questions can be\nfound at: https://www.debian.org/security/\n\nMailing list: debian-security-announce@lists.debian.org\n-----BEGIN PGP SIGNATURE-----\n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\ne3g3nA1rbB1jlx6cvPqWBFItXW8800mJ0CXHb8EN8jKdB5BnooY=\n=6KYM\n-----END PGP SIGNATURE-----\n. \n\n\n\n\nDescription:\n\nVarnish Cache is a high-performance HTTP accelerator.

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

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

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."

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
Severity ?
