02 Description

misp-modules: Shell Command Injection in MISP cisco_firesight_manager_ACL_rule_export Module via Unescaped Attribute Values

03 Exploitation and scoring

Exploitation

Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.

SSVC decision

ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
AutomatablenoAt least one step from reconnaissance to exploitation cannot be reliably automated.
Technical ImpactpartialSuccessful exploitation gives limited control of the vulnerable component.

CISA publishes the decision points, not a final SSVC decision. The decision also depends on mission and well-being impact, which is a property of your deployment rather than of the vulnerability.

EPSS probability

0.32% probability of exploitation activity in the next 30 days.

EPSS percentile

Equal to or higher than the score of 24.6% of scored records. A rank, not a probability.

NVD base score

6.3 (CVSS v4.0), scored by the NVD independently of the CNA.

07 Remediation

All user-controlled and configuration values interpolated into the generated shell script are now passed through Python's shlex.quote() function, which produces a safely quoted string that cannot be broken out of by embedded shell metacharacters. For the JSON access-rule block that embeds multiple attribute values within a single shell assignment, the JSON content is first assembled as plain text and then the entire assembled string is shlex-quoted once, preventing stray quote characters from corrupting the outer quoting. The 'config' variable is now initialized to an empty dictionary before the conditional assignment, eliminating the NameError.
