CVE Severity Published▾ Status Exploitation Description
CVE-2020-13956 Medium 2020-12-02 Outside Waratek scope No public exploit Apache HttpClient versions prior to version 4.5.13 and 5.0.3 can misinterpret malformed authority component in request URIs passed to the library as java.net.URI object and pick the wrong target host for request execution.
CVE-2020-27218 Medium 2020-11-28 No exploit published No public exploit In Eclipse Jetty version 9.4.0.RC0 to 9.4.34.v20201102, 10.0.0.alpha0 to 10.0.0.beta2, and 11.0.0.alpha0 to 11.0.0.beta2, if GZIP request body inflation is enabled and requests from different clients are multiplexed onto a single connection, and if an attacker can send a request with a body that is received entirely but not consumed by the application, then a subsequent request on the same connection will see that body prepended to its body. The attacker will not see any data but may inject data into the body of the subsequent request.
CVE-2020-15250 Medium 2020-10-12 Protected by Waratek No public exploit In JUnit4 from version 4.7 and before 4.13.1, the test rule TemporaryFolder contains a local information disclosure vulnerability. On Unix like systems, the system's temporary directory is shared between all users on that system. Because of this, when files and directories are written into this directory they are, by default, readable by other users on that same system. This vulnerability does not allow other users to overwrite the contents of these directories or files. This is purely an information disclosure vulnerability. This vulnerability impacts you if the JUnit tests write sensitive information, like API keys or passwords, into the temporary folder, and the JUnit tests execute in an environment where the OS has other untrusted users. Because certain JDK file system APIs were only added in JDK 1.7, this this fix is dependent upon the version of the JDK you are using. For Java 1.7 and higher users: this vulnerability is fixed in 4.13.1. For Java 1.6 and lower users: no patch is available, you must use the workaround below. If you are unable to patch, or are stuck running on Java 1.6, specifying the `java.io.tmpdir` system environment variable to a directory that is exclusively owned by the executing user will fix this vulnerability. For more information, including an example of vulnerable code, see the referenced GitHub Security Advisory.
CVE-2020-5421 Medium 2020-09-19 No exploit published No public exploit In Spring Framework versions 5.2.0 - 5.2.8, 5.1.0 - 5.1.17, 5.0.0 - 5.0.18, 4.3.0 - 4.3.28, and older unsupported versions, the protections against RFD attacks from CVE-2015-5211 may be bypassed depending on the browser used through the use of a jsessionid path parameter.
CVE-2020-24977 Medium 2020-09-04 Outside Waratek scope No public exploit GNOME project libxml2 v2.9.10 has a global buffer over-read vulnerability in xmlEncodeEntitiesInternal at libxml2/entities.c. The issue has been fixed in commit 50f06b3e.
CVE-2020-16135 Medium 2020-07-29 Not applicable No public exploit libssh 0.9.4 has a NULL pointer dereference in tftpserver.c if ssh_buffer_new returns NULL.
CVE-2020-14155 Medium 2020-06-15 Not applicable No public exploit libpcre in PCRE before 8.44 allows an integer overflow via a large number after a (?C substring.
CVE-2020-13434 Medium 2020-05-24 Not applicable No public exploit SQLite through 3.32.0 has an integer overflow in sqlite3_str_vappendf in printf.c.
CVE-2020-11022 Medium 2020-04-29 Outside Waratek scope Exploited In jQuery starting with 1.12.0 and before 3.5.0, passing HTML from untrusted sources - even after sanitizing it - to one of jQuery's DOM manipulation methods (i.e. .html(), .append(), and others) may execute untrusted code. This problem is patched in jQuery 3.5.0.
CVE-2019-14862 Medium 2020-01-02 Outside Waratek scope No public exploit There is a vulnerability in knockout before version 3.5.0-beta, where after escaping the context of the web application, the web application delivers data to its users along with other trusted dynamic content, without validating it.
CVE-2019-3740 Medium 2019-09-18 Outside Waratek scope No public exploit RSA BSAFE Crypto-J versions prior to 6.2.5 are vulnerable to an Information Exposure Through Timing Discrepancy vulnerabilities during DSA key generation. A malicious remote attacker could potentially exploit those vulnerabilities to recover DSA keys.
CVE-2019-3799 Medium 2019-05-06 Protected by Waratek Working exploit published Spring Cloud Config, versions 2.1.x prior to 2.1.2, versions 2.0.x prior to 2.0.4, and versions 1.4.x prior to 1.4.6, and older unsupported versions allow applications to serve arbitrary configuration files through the spring-cloud-config-server module. A malicious user, or attacker, can send a request using a specially crafted URL that can lead a directory traversal attack.
CVE-2018-11212 Medium 2018-05-16 Not applicable No public exploit An issue was discovered in libjpeg 9a and 9d. The alloc_sarray function in jmemmgr.c allows remote attackers to cause a denial of service (divide-by-zero error) via a crafted file.
