Description

This security bulletin contains information about 7 vulnerabilities.

1) Resource exhaustion (CVE-ID: CVE-2025-61772)

CWE-ID: CWE-400 - Resource exhaustion

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 application does not properly control consumption of internal resources in Rack::Multipart::Parser when handling multipart headers. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.

2) Resource exhaustion (CVE-ID: CVE-2025-61771)

CWE-ID: CWE-400 - Resource exhaustion

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 application does not properly control consumption of internal resources in Rack::Multipart::Parser when handling file parts. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.

3) Resource exhaustion (CVE-ID: CVE-2025-61770)

CWE-ID: CWE-400 - Resource exhaustion

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 application does not properly control consumption of internal resources in Rack::Multipart::Parser. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.

4) Use-after-free (CVE-ID: CVE-2025-49844)

CWE-ID: CWE-416 - Use After Free

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

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error. A remote user can use a specially crafted Lua script to manipulate the garbage collector and execute arbitrary code on the target system.

5) Integer overflow (CVE-ID: CVE-2025-46817)

CWE-ID: CWE-190 - Integer overflow

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

The vulnerability allows a remote user to execute arbitrary code on the target system.

The vulnerability exists due to integer overflow when processing Lua scripts. A remote user can pass specially crafted data to the application, trigger an integer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

6) Improper authentication (CVE-ID: CVE-2025-46818)

CWE-ID: CWE-287 - Improper Authentication

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

The vulnerability allows a remote user to escalate privileges within the application.

The vulnerability exists due to an error when handling Lua scripts. A remote user can manipulate different LUA objects and potentially run their own code in the context of another user.

7) Out-of-bounds read (CVE-ID: CVE-2025-46819)

CWE-ID: CWE-125 - Out-of-bounds read

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

The vulnerability allows a remote user to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition when processing Lua scripts. A remote user  can trigger an out-of-bounds read error and read contents of memory on the system or perform a denial of service (DoS) attack.
