CVSS: 7.8EPSS: 80%CPEs: 24EXPL: 2CVE-2021-28165 – jetty: Resource exhaustion when receiving an invalid large TLS frame
https://notcve.org/view.php?id=CVE-2021-28165
In Eclipse Jetty 7.2.2 to 9.4.38, 10.0.0.alpha0 to 10.0.1, and 11.0.0.alpha0 to 11.0.1, CPU usage can reach 100% upon receiving a large invalid TLS frame. En Eclipse Jetty versiones 7.2.2 hasta 9.4.38, versiones 10.0.0.alpha0 hasta 10.0.1 y versiones 11.0.0.alpha0 hasta 11.0.1, el uso de CPU puede alcanzar el 100% al recibir una gran trama TLS no válida. When using SSL/TLS with Jetty, either with HTTP/1.1, HTTP/2, or WebSocket, the server may receive an invalid large (greater than 17408) TLS frame that is incorrectly handled, causing high CPU resources utilization. The highest threat from this vulnerability is to service availability. • https://github.com/uthrasri/CVE-2021-28165 http://www.openwall.com/lists/oss-security/2021/04/20/3 https://github.com/eclipse/jetty.project/security/advisories/GHSA-26vr-8j45-3r4w https://lists.apache.org/thread.html/r002258611ed0c35b82b839d284b43db9dcdec120db8afc1c993137dc%40%3Cnotifications.zookeeper.apache.org%3E https://lists.apache.org/thread.html/r03ca0b69db1e3e5f72fe484b71370d537cd711cbf334e2913332730a%40%3Cissues.spark.apache.org%3E https://lists.apache.org/thread.html/r05db8e0ef01e1280cc7543575ae0fa1c2b4d06a8b928916ef65dd2ad%40%3Creviews.spark • CWE-400: Uncontrolled Resource Consumption CWE-551: Incorrect Behavior Order: Authorization Before Parsing and Canonicalization CWE-755: Improper Handling of Exceptional Conditions •
CVSS: 4.0EPSS: 0%CPEs: 33EXPL: 1CVE-2021-28163 – jetty: Symlink directory exposes webapp directory contents
https://notcve.org/view.php?id=CVE-2021-28163
In Eclipse Jetty 9.4.32 to 9.4.38, 10.0.0.beta2 to 10.0.1, and 11.0.0.beta2 to 11.0.1, if a user uses a webapps directory that is a symlink, the contents of the webapps directory is deployed as a static webapp, inadvertently serving the webapps themselves and anything else that might be in that directory. En Eclipse Jetty versiones 9.4.32 hasta 9.4.38, versiones 10.0.0.beta2 hasta 10.0.1 y versiones 11.0.0.beta2 hasta 11.0.1, si un usuario usa un directorio de aplicaciones web que es un enlace simbólico, el contenido del directorio de aplicaciones web se implementa como una aplicación web estática, sin darse cuenta, sirviendo las aplicaciones web en sí y cualquier otra cosa que pueda estar en ese directorio. If the ${jetty.base} directory or the ${jetty.base}/webapps directory is a symlink the contents of the ${jetty.base}/webapps directory may be deployed as a static web application, exposing the content of the directory for download. The highest threat from this vulnerability is to data confidentiality. • https://github.com/eclipse/jetty.project/security/advisories/GHSA-j6qj-j888-vvgq https://lists.apache.org/thread.html/r0841b06b48324cfc81325de3c05a92e53f997185f9d71ff47734d961%40%3Cissues.solr.apache.org%3E https://lists.apache.org/thread.html/r111f1ce28b133a8090ca4f809a1bdf18a777426fc058dc3a16c39c66%40%3Cissues.solr.apache.org%3E https://lists.apache.org/thread.html/r2ea2f0541121f17e470a0184843720046c59d4bde6d42bf5ca6fad81%40%3Cissues.solr.apache.org%3E https://lists.apache.org/thread.html/r4a66bfbf62281e31bc1345ebecbfd96f35199eecd77bfe4e903e906f%40%3Cissues.ignite.apache.org%3 • CWE-59: Improper Link Resolution Before File Access ('Link Following') CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 5.9EPSS: 0%CPEs: 205EXPL: 0CVE-2021-3449 – NULL pointer deref in signature_algorithms processing
https://notcve.org/view.php?id=CVE-2021-3449
An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack. A server is only vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS clients are not impacted by this issue. All OpenSSL 1.1.1 versions are affected by this issue. • http://www.openwall.com/lists/oss-security/2021/03/27/1 http://www.openwall.com/lists/oss-security/2021/03/27/2 http://www.openwall.com/lists/oss-security/2021/03/28/3 http://www.openwall.com/lists/oss-security/2021/03/28/4 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://cert-portal.siemens.com/productcert/pdf/ssa-772220.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=fb9fa6b51defd48157eeb207f52181f735d96148 https://kb.pulse • CWE-476: NULL Pointer Dereference •
CVSS: 7.5EPSS: 0%CPEs: 3EXPL: 3CVE-2021-21267 – Regular Expression Denial-of-Service in npm schema-inspector
https://notcve.org/view.php?id=CVE-2021-21267
Schema-Inspector is an open-source tool to sanitize and validate JS objects (npm package schema-inspector). In before version 2.0.0, email address validation is vulnerable to a denial-of-service attack where some input (for example `a@0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.`) will freeze the program or web browser page executing the code. This affects any current schema-inspector users using any version to validate email addresses. Users who do not do email validation, and instead do other types of validation (like string min or max length, etc), are not affected. Users should upgrade to version 2.0.0, which uses a regex expression that isn't vulnerable to ReDoS. • https://gist.github.com/mattwelke/b7f42424680a57b8161794ad1737cd8f https://github.com/schema-inspector/schema-inspector/security/advisories/GHSA-f38p-c2gq-4pmr https://security.netapp.com/advisory/ntap-20210528-0006 https://www.npmjs.com/package/schema-inspector • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption •
