Multiple vulnerabilities in IBM Robotic Process Automation for Cloud Pak

1) Out-of-bounds write

EUVDB-ID: #VU63487

Risk: High

CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-1785

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code

The vulnerability exists due to a boundary error when processing untrusted input in vim_regsub_both() function. A remote attacker can create a specially crafted file, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.

Mitigation

Install update from vendor's website.

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Out-of-bounds write

EUVDB-ID: #VU64506

Risk: Low

CVSSv3.1: 6.1 [CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-1897

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: No

Description

The vulnerability allows a local attacker to execute arbitrary code on the system.

The vulnerability exists due to Illegal memory access and leads to an out-of-bounds write vulnerability in the vim_regsub_both() function. A local attacker can trick the victim into opening a specially crafted file, leading to a system crash or code execution.

Mitigation

Install update from vendor's website.

Q & A

Can this vulnerability be exploited remotely?

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

3) Out-of-bounds read

EUVDB-ID: #VU64508

Risk: Low

CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-1927

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

Exploit availability: No

Description

The vulnerability allows a local attacker to execute arbitrary code on the system.

The vulnerability exists due to Illegal memory access and leads to a buffer over-read vulnerability in the utf_ptr2char() function. A local attacker can trick the victim into opening a specially crafted file, trigger out-of-bounds read error and execute arbitrary code on the system.

Mitigation

Install update from vendor's website.
