CVSS: 5.3EPSS: 0%CPEs: 6EXPL: 1CVE-2020-10933 – ruby: BasicSocket#read_nonblock method leads to information disclosure
https://notcve.org/view.php?id=CVE-2020-10933
An issue was discovered in Ruby 2.5.x through 2.5.7, 2.6.x through 2.6.5, and 2.7.0. If a victim calls BasicSocket#read_nonblock(requested_size, buffer, exception: false), the method resizes the buffer to fit the requested size, but no data is copied. Thus, the buffer string provides the previous value of the heap. This may expose possibly sensitive data from the interpreter. Se descubrió un problema en Ruby versiones 2.5.x hasta 2.5.7, versiones 2.6.x hasta 2.6.5, y versión 2.7.0. • https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/F4TNVTT66VPRMX5UZYSDGSVRXKKDDDU5 https://security.netapp.com/advisory/ntap-20200625-0001 https://www.debian.org/security/2020/dsa-4721 https://www.ruby-lang.org/en/news/2020/03/31/heap-exposure-in-socket-cve-2020-10933 https://access.redhat.com/security/cve/CVE-2020-10933 https://bugzilla.redhat.com/show_bug.cgi?id=1833291 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-908: Use of Uninitialized Resource •
CVSS: 7.5EPSS: 0%CPEs: 10EXPL: 0CVE-2020-10663 – rubygem-json: Unsafe object creation vulnerability in JSON
https://notcve.org/view.php?id=CVE-2020-10663
The JSON gem through 2.2.0 for Ruby, as used in Ruby 2.4 through 2.4.9, 2.5 through 2.5.7, and 2.6 through 2.6.5, has an Unsafe Object Creation Vulnerability. This is quite similar to CVE-2013-0269, but does not rely on poor garbage-collection behavior within Ruby. Specifically, use of JSON parsing methods can lead to creation of a malicious object within the interpreter, with adverse effects that are application-dependent. La gema JSON versiones hasta 2.2.0 para Ruby, como es usado en Ruby versiones 2.4 hasta 2.4.9, versiones 2.5 hasta 2.5.7 y versiones 2.6 hasta 2.6.5, tiene una Vulnerabilidad de Creación de Objetos No Segura. Esto es bastante similar a CVE-2013-0269, pero no se basa en un comportamiento inapropiado garbage-collection dentro de Ruby. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00004.html http://seclists.org/fulldisclosure/2020/Dec/32 https://lists.apache.org/thread.html/r37c0e1807da7ff2bdd028bbe296465a6bbb99e2320dbe661d5d8b33b%40%3Cissues.zookeeper.apache.org%3E https://lists.apache.org/thread.html/r3b04f4e99a19613f88ae088aa18cd271231a3c79dfff8f5efa8cda61%40%3Cissues.zookeeper.apache.org%3E https://lists.apache.org/thread.html/r5f17bfca1d6e7f4b33ae978725b2fd62a9f1b3111696eafa9add802d%40%3Cissues.zookeeper.apache.org%3E https://lists.apache.org/thread.html/r8d2e174230f6d26e16c0 • CWE-20: Improper Input Validation CWE-94: Improper Control of Generation of Code ('Code Injection') •
CVSS: 7.5EPSS: 1%CPEs: 11EXPL: 0CVE-2020-5247 – HTTP Response Splitting in Puma
https://notcve.org/view.php?id=CVE-2020-5247
In Puma (RubyGem) before 4.3.2 and before 3.12.3, if an application using Puma allows untrusted input in a response header, an attacker can use newline characters (i.e. `CR`, `LF` or`/r`, `/n`) to end the header and inject malicious content, such as additional headers or an entirely new response body. This vulnerability is known as HTTP Response Splitting. While not an attack in itself, response splitting is a vector for several other attacks, such as cross-site scripting (XSS). This is related to CVE-2019-16254, which fixed this vulnerability for the WEBrick Ruby web server. • https://github.com/puma/puma/security/advisories/GHSA-84j7-475p-hp8v https://lists.debian.org/debian-lts-announce/2022/05/msg00034.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BMJ3CGZ3DLBJ5WUUKMI5ZFXFJQMXJZIK https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DIHVO3CQMU7BZC7FCTSRJ33YDNS3GFPK https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/NJ3LL5F5QADB6LM46GXZETREAKZMQNRD https://owasp.org/www-communi • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Request/Response Splitting') •
