CVE Severity Published▾ Status Exploitation Description
CVE-2021-2277 High 2021-04-22 No exploit published No public exploit Vulnerability in the Oracle Coherence product of Oracle Fusion Middleware (component: Core). Supported versions that are affected are 3.7.1.0, 12.1.3.0.0, 12.2.1.3.0, 12.2.1.4.0 and 14.1.1.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Coherence. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Coherence accessible data. CVSS 3.1 Base Score 7.5 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).
CVE-2021-2157 High 2021-04-22 No exploit published No public exploit Vulnerability in the Oracle WebLogic Server product of Oracle Fusion Middleware (component: TopLink Integration). Supported versions that are affected are 10.3.6.0.0, 12.1.3.0.0, 12.2.1.3.0 and 12.2.1.4.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle WebLogic Server. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle WebLogic Server accessible data. CVSS 3.1 Base Score 7.5 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).
CVE-2020-11987 High 2021-02-24 No exploit published No public exploit Apache Batik 1.13 is vulnerable to server-side request forgery, caused by improper input validation by the NodePickerPanel. By using a specially-crafted argument, an attacker could exploit this vulnerability to cause the underlying server to make arbitrary GET requests.
CVE-2020-28052 High 2020-12-18 No exploit published No public exploit An issue was discovered in Legion of the Bouncy Castle BC Java 1.65 and 1.66. The OpenBSDBCrypt.checkPassword utility method compared incorrect data when checking the password, allowing incorrect passwords to indicate they were matching with previously hashed ones that were different.
CVE-2020-25649 High 2020-12-03 Protected by Waratek No public exploit A flaw was found in FasterXML Jackson Databind, where it did not have entity expansion secured properly. This flaw allows vulnerability to XML external entity (XXE) attacks. The highest threat from this vulnerability is data integrity.
CVE-2020-26217 High 2020-11-16 Protected by Waratek Working exploit published 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. The issue is fixed in version 1.4.14.
CVE-2019-17566 High 2020-11-12 Protected by Waratek No public exploit Apache Batik is vulnerable to server-side request forgery, caused by improper input validation by the "xlink:href" attributes. By using a specially-crafted argument, an attacker could exploit this vulnerability to cause the underlying server to make arbitrary GET requests.
CVE-2020-11979 High 2020-10-01 No exploit published No public exploit As mitigation for CVE-2020-1945 Apache Ant 1.10.8 changed the permissions of temporary files it created so that only the current user was allowed to access them. Unfortunately the fixcrlf task deleted the temporary file and created a new one without said protection, effectively nullifying the effort. This would still allow an attacker to inject modified source files into the build process.
CVE-2020-24750 High 2020-09-17 Protected by Waratek No public exploit FasterXML jackson-databind 2.x before 2.9.10.6 mishandles the interaction between serialization gadgets and typing, related to com.pastdev.httpcomponents.configuration.JndiConfiguration.
CVE-2020-11994 High 2020-07-08 No exploit published No public exploit Server-Side Template Injection and arbitrary file disclosure on Camel templating components
CVE-2019-12402 High 2019-08-30 No exploit published No public exploit The file name encoding algorithm used internally in Apache Commons Compress 1.15 to 1.18 can get into an infinite loop when faced with specially crafted inputs. This can lead to a denial of service attack if an attacker can choose the file names inside of an archive created by Compress.
CVE-2019-10086 High 2019-08-20 Protected by Waratek No public exploit In Apache Commons Beanutils 1.9.2, a special BeanIntrospector class was added which allows suppressing the ability for an attacker to access the classloader via the class property available on all Java objects. We, however were not using this by default characteristic of the PropertyUtilsBean.
CVE-2018-1000180 High 2018-06-05 No exploit published No public exploit Bouncy Castle BC 1.54 - 1.59, BC-FJA 1.0.0, BC-FJA 1.0.1 and earlier have a flaw in the Low-level interface to RSA key pair generator, specifically RSA Key Pairs generated in low-level API with added certainty may have less M-R tests than expected. This appears to be fixed in versions BC 1.60 beta 4 and later, BC-FJA 1.0.2 and later.
CVE-2017-12626 High 2018-01-29 No exploit published No public exploit Apache POI in versions prior to release 3.17 are vulnerable to Denial of Service Attacks: 1) Infinite Loops while parsing crafted WMF, EMF, MSG and macros (POI bugs 61338 and 61294), and 2) Out of Memory Exceptions while parsing crafted DOC, PPT and XLS (POI bugs 52372 and 61295).
