Description

This security bulletin contains information about 2 vulnerabilities.


1) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2019-10136)

CWE-ID: CWE-347 - Improper Verification of Cryptographic Signature

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to bypass signature validation process.

The vulnerability exists due to the affected software does not safely compute client token checksums. A remote attacker with a valid, but expired, authenticated set of headers can move some digits around, artificially extending the session validity without modifying the checksum.


2) XML External Entity injection (CVE-ID: CVE-2020-1693)

CWE-ID: CWE-611 - Improper Restriction of XML External Entity Reference ('XXE')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied XML input in the "/rpc/api" endpoint. A remote attacker can pass a specially crafted XML code to the affected application, retrieve the content of certain files and trigger a denial of service, or in certain circumstances, execute arbitrary code on the Spacewalk server.
