CVE-2026-32768 (GCVE-0-2026-32768)
Vulnerability from cvelistv5
Published

Modified
2026-03-20 15:58
Severity ?
7.9 (High) - CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:H
CWE
  • CWE-284 - Improper Access Control
Summary
Chall-Manager is a platform-agnostic system able to start Challenges on Demand of a player. In versions prior to 0.6.5, due to a miswritten NetworkPolicy, a malicious actor can pivot from an instance to any Pod out of the origin namespace. This breaks the security-by-default property expected as part of the deployment program, leading to a potential lateral movement. In the specific case of sdk/kubernetes.Kompose it does not isolate the instances. This issue has been fixed in version 0.6.5.

CVE-2025-53634 (GCVE-0-2025-53634)
Vulnerability from cvelistv5
Published
2025-07-10 19:39
Modified
2025-07-10 20:26
Severity ?
8.7 (High) - 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
CWE
  • CWE-770 - Allocation of Resources Without Limits or Throttling
Summary
Chall-Manager is a platform-agnostic system able to start Challenges on Demand of a player. The HTTP Gateway processes headers, but with no timeout set. With a slow loris attack, an attacker could cause Denial of Service (DoS). Exploitation does not require authentication nor authorization, so anyone can exploit it. It should nonetheless not be exploitable as it is highly recommended to bury Chall-Manager deep within the infrastructure due to its large capabilities, so no users could reach the system. Patch has been implemented by commit 1385bd8 and shipped in v0.1.4.

CVE-2025-53633 (GCVE-0-2025-53633)
Vulnerability from cvelistv5
Published

Severity ?
8.7 (High) - 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
CWE
  • CWE-405 - Asymmetric Resource Consumption (Amplification)
Summary
Chall-Manager is a platform-agnostic system able to start Challenges on Demand of a player. When decoding a scenario (i.e. a zip archive), the size of the decoded content is not checked, potentially leading to zip bombs decompression. Exploitation does not require authentication nor authorization, so anyone can exploit it. It should nonetheless not be exploitable as it is highly recommended to bury Chall-Manager deep within the infrastructure due to its large capabilities, so no users could reach the system. Patch has been implemented by commit 14042aa and shipped in v0.1.4.

CVE-2025-53632 (GCVE-0-2025-53632)
Vulnerability from cvelistv5
Published
2025-07-10 19:36
Modified
2025-07-10 20:31
Severity ?
8.8 (High) - CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N
CWE
  • CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Summary
Chall-Manager is a platform-agnostic system able to start Challenges on Demand of a player. When decoding a scenario (i.e. a zip archive), the path of the file to write is not checked, potentially leading to zip slips. Exploitation does not require authentication nor authorization, so anyone can exploit it. It should nonetheless not be exploitable as it is highly recommended to bury Chall-Manager deep within the infrastructure due to its large capabilities, so no users could reach the system. Patch has been implemented by commit 47d188f and shipped in v0.1.4.
