Description
This security bulletin contains information about 6 vulnerabilities.
1) Reachable assertion (CVE-ID: CVE-2019-15604)
CWE-ID: CWE-617 - Reachable Assertion
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of X509 certificates in X509V3_EXT_print(). A remote attacker can supply a specially crafted client certificate to the application and perform a denial of service attack.
2) HTTP request smuggling (CVE-ID: CVE-2019-15605)
CWE-ID: CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform HTTP request smuggling attack.
The vulnerability exists due to insufficient validation of Transfer-Encoding header. A remote attacker can send a specially crafted HTTP request to the application and perform a request smuggling attack.
3) Input validation error (CVE-ID: CVE-2019-15606)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to manipulate HTTP headers.
The vulnerability exists due to insufficient validation of a trailing white-space character in the request headers. A remote attacker can send a specially crafted HTTP request to the application and bypass certain security restrictions.
4) Symlink following (CVE-ID: CVE-2019-16775)
CWE-ID: CWE-61 - UNIX Symbolic Link (Symlink) Following
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to perform directory traversal attacks.
Versions of the npm CLI prior to 6.13.3 are vulnerable to a symlink reference outside of node_modules. It is possible for packages to create symlinks to files outside of the node_modules folder through the bin field upon installation. A properly constructed entry in the package.json bin field would allow a package publisher to create a symlink pointing to arbitrary files on a user’s system when the package is installed. Only files accessible by the user running the npm install are affected.
5) Improper input validation (CVE-ID: CVE-2019-16776)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote authenticated user to read and manipulate data.
The vulnerability exists due to improper input validation within the JavaScript (Node.js) component in Oracle GraalVM Enterprise Edition. A remote authenticated user can exploit this vulnerability to read and manipulate data.
6) Path traversal (CVE-ID: CVE-2019-16777)
CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences. The software fails to prevent existing globally-installed binaries to be overwritten by other package installations. For example, if a package was installed globally and created a serve binary, any subsequent installs of packages that also create a serve binary would overwrite the first binary. This only affects files in /usr/local/bin
A remote attacker can overwrite arbitrary files on the system.
