CVSS: 7.8EPSS: 0%CPEs: 13EXPL: 0CVE-2019-9854 – Unsafe URL assembly flaw in allowed script location check
https://notcve.org/view.php?id=CVE-2019-9854
LibreOffice has a feature where documents can specify that pre-installed macros can be executed on various script events such as mouse-over, document-open etc. Access is intended to be restricted to scripts under the share/Scripts/python, user/Scripts/python sub-directories of the LibreOffice install. Protection was added, to address CVE-2019-9852, to avoid a directory traversal attack where scripts in arbitrary locations on the file system could be executed by employing a URL encoding attack to defeat the path verification step. However this protection could be bypassed by taking advantage of a flaw in how LibreOffice assembled the final script URL location directly from components of the passed in path as opposed to solely from the sanitized output of the path verification step. This issue affects: Document Foundation LibreOffice 6.2 versions prior to 6.2.7; 6.3 versions prior to 6.3.1. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00067.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00055.html https://bugzilla.redhat.com/show_bug.cgi?id=1769907 https://lists.debian.org/debian-lts-announce/2019/10/msg00005.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/XQKKOIY2DMZCXJINOLIQXD2NWISDKK3N https://seclists.org/bugtraq/2019/Sep/17 https://usn.ubuntu.com/4138-1 https://www.debian.org/security/201 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-284: Improper Access Control •

LibreOffice has a feature where documents can specify that pre-installed macros can be executed on various script events such as mouse-over, document-open etc. Access is intended to be restricted to scripts under the share/Scripts/python, user/Scripts/python sub-directories of the LibreOffice install. Protection was added, to address CVE-2018-16858, to avoid a directory traversal attack where scripts in arbitrary locations on the file system could be executed. However this new protection could be bypassed by a URL encoding attack. In the fixed versions, the parsed url describing the script location is correctly encoded before further processing. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00067.html https://lists.debian.org/debian-lts-announce/2019/10/msg00005.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PMEGUWMWORC3DOVEHVXLFT3A5RSCMLBH https://seclists.org/bugtraq/2019/Aug/28 https://seclists.org/bugtraq/2019/Sep/17 https://usn.ubuntu.com/4102-1 https://www.debian.org/security/2019/dsa-4 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-116: Improper Encoding or Escaping of Output •
CVSS: 9.8EPSS: 96%CPEs: 10EXPL: 1CVE-2019-9851 – LibreLogo global-event script execution
https://notcve.org/view.php?id=CVE-2019-9851
LibreOffice is typically bundled with LibreLogo, a programmable turtle vector graphics script, which can execute arbitrary python commands contained with the document it is launched from. Protection was added, to address CVE-2019-9848, to block calling LibreLogo from document event script handers, e.g. mouse over. However LibreOffice also has a separate feature where documents can specify that pre-installed scripts can be executed on various global script events such as document-open, etc. In the fixed versions, global script event handlers are validated equivalently to document script event handlers. This issue affects: Document Foundation LibreOffice versions prior to 6.2.6. • https://www.exploit-db.com/exploits/47298 http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00067.html http://packetstormsecurity.com/files/154168/LibreOffice-Macro-Python-Code-Execution.html https://lists.debian.org/debian-lts-announce/2019/10/msg00005.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PMEGUWMWORC3DOVEHVXLFT3A5RSCMLBH https://seclists.org/bugtraq/2019/Aug/28 htt • CWE-20: Improper Input Validation CWE-94: Improper Control of Generation of Code ('Code Injection') •

LibreOffice is typically bundled with LibreLogo, a programmable turtle vector graphics script, which can execute arbitrary python commands contained with the document it is launched from. LibreOffice also has a feature where documents can specify that pre-installed scripts can be executed on various document script events such as mouse-over, etc. Protection was added, to address CVE-2019-9848, to block calling LibreLogo from script event handers. However an insufficient url validation vulnerability in LibreOffice allowed malicious to bypass that protection and again trigger calling LibreLogo from script event handlers.

CVSS: 4.3EPSS: 0%CPEs: 9EXPL: 1CVE-2019-9849 – libreoffice: Remote resources protection module not applied to bullet graphics
https://notcve.org/view.php?id=CVE-2019-9849
LibreOffice has a 'stealth mode' in which only documents from locations deemed 'trusted' are allowed to retrieve remote resources. This mode is not the default mode, but can be enabled by users who want to disable LibreOffice's ability to include remote resources within a document. A flaw existed where bullet graphics were omitted from this protection prior to version 6.2.5. This issue affects: Document Foundation LibreOffice versions prior to 6.2.5. LibreOffice presenta un "stealth mode" en el que solo los documentos desde ubicaciones consideradas "trusted" pueden recuperar recursos remotos. • https://github.com/mbadanoiu/CVE-2019-9849 http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00067.html http://www.securityfocus.com/bid/109374 https://lists.debian.org/debian-lts-announce/2019/10/msg00005.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PMEGUWMWORC3DOVEHVXLFT3A5RSCMLBH https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message& • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
