https://notcve.org/view.php?id=CVE-2020-26258
XStream is a Java library to serialize objects to XML and back again. In XStream before version 1.4.15, a Server-Side Forgery Request vulnerability can be activated when unmarshalling. The vulnerability may allow a remote attacker to request data from internal resources that are not publicly available only by manipulating the processed input stream. If you rely on XStream's default blacklist of the Security Framework, you will have to use at least version 1.4.15. The reported vulnerability does not exist if running Java 15 or higher. • https://github.com/Al1ex/CVE-2020-26258 https://github.com/x-stream/xstream/security/advisories/GHSA-4cch-wxpw-8p28 https://lists.apache.org/thread.html/r97993e3d78e1f5389b7b172ba9f308440830ce5f051ee62714a0aa34%40%3Ccommits.struts.apache.org%3E https://lists.debian.org/debian-lts-announce/2020/12/msg00042.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/22KVR6B5IZP3BGQ3HPWIO2FWWCKT3DHP https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PVPHZA • CWE-918: Server-Side Request Forgery (SSRF) •

XStream is a Java library to serialize objects to XML and back again. In XStream before version 1.4.15, is vulnerable to an Arbitrary File Deletion on the local host when unmarshalling. The vulnerability may allow a remote attacker to delete arbitrary know files on the host as log as the executing process has sufficient rights only by manipulating the processed input stream. If you rely on XStream's default blacklist of the Security Framework, you will have to use at least version 1.4.15.

XStream before version 1.4.14 is vulnerable to Remote Code Execution.The vulnerability may allow a remote attacker to run arbitrary shell commands only by manipulating the processed input stream. Only users who rely on blocklists are affected. Anyone using XStream's Security Framework allowlist is not affected. The linked advisory provides code workarounds for users who cannot upgrade.

It was found that xstream API version 1.4.10 before 1.4.11 introduced a regression for a previous deserialization flaw. If the security framework has not been initialized, it may allow a remote attacker to run arbitrary shell commands when unmarshalling XML or any supported format. e.g. JSON.

Si el framework security no ha sido inicializado, puede permitir a un atacante remoto ejecutar comandos de shell arbitrarios cuando se deserializa un XML o cualquier formato compatible. p.ej. • http://x-stream.github.io/changes.html#1.4.11 https://access.redhat.com/errata/RHSA-2019:3892 https://access.redhat.com/errata/RHSA-2019:4352 https://access.redhat.com/errata/RHSA-2020:0445 https://access.redhat.com/errata/RHSA-2020:0727 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-10173 https://www.oracle.com//security-alerts/cpujul2021.html https://www.oracle.com/security-alerts/cpuApr2021.html https://www.oracle.com/security-alerts/cpuapr2020.html https:/&# • CWE-94: Improper Control of Generation of Code ('Code Injection') CWE-502: Deserialization of Untrusted Data •
CVSS: 7.5EPSS: 74%CPEs: 3EXPL: 0CVE-2017-7957 – XStream: DoS when unmarshalling void type
https://notcve.org/view.php?id=CVE-2017-7957
XStream through 1.4.9, when a certain denyTypes workaround is not used, mishandles attempts to create an instance of the primitive type 'void' during unmarshalling, leading to a remote application crash, as demonstrated by an xstream.fromXML("<void/>") call. XStream a través de 1.4.9, cuando no se utiliza una solución de denyTypes, mishandles intenta crear una instancia del tipo primitivo 'void' durante unmarshalling, dando lugar a un fallo de aplicación remota, como lo demuestra una llamda a xstream.fromXML (" > "). It was found that XStream contains a vulnerability that allows a maliciously crafted file to be parsed successfully which could cause an application crash. The crash occurs if the file that is being fed into XStream input stream contains an instances of the primitive type 'void'. An attacker could use this flaw to create a denial of service on the target system. • http://www.debian.org/security/2017/dsa-3841 http://www.securityfocus.com/bid/100687 http://www.securitytracker.com/id/1039499 http://x-stream.github.io/CVE-2017-7957.html https://access.redhat.com/errata/RHSA-2017:1832 https://access.redhat.com/errata/RHSA-2017:2888 https://access.redhat.com/errata/RHSA-2017:2889 https://exchange.xforce.ibmcloud.com/vulnerabilities/125800 https://www-prd-trops.events.ibm.com/node/715749 https://access.redhat.com/security/cve/CVE-2017 • CWE-20: Improper Input Validation •
